DETAILED DESCRIPTION

The disclosed embodiments include radio-frequency identification (RFID) tags, each with unique identifiers. The RFID tag is used in a data- and command delivery mechanism to query, unlock, and reconfigure a hardware resource. Information items stored on the RFID tag includes the process genealogy and the performance capabilities of the hardware resource. Control instructions and methods that are stored in non-volatile random-access memory (NVRAM) in the RFID tag, is used to be read and to reconfigure settings in the hardware resource. Microcode-driven firmware is also used as RFID tag readers and programmers such as by a physical connection, e.g., a serial bus.

Reference will now be made to the drawings wherein like structures may be provided with like suffix reference designations. In order to show the structures of various embodiments most clearly, the drawings included herein are diagrammatic representations of integrated circuit structures. Thus, the actual appearance of the fabricated structures, for example in a photomicrograph, may appear different while still incorporating the claimed structures of the illustrated embodiments. Moreover, the drawings may only show the structures necessary to understand the illustrated embodiments. Additional structures known in the art may not have been included to maintain the clarity of the drawings. Although a processor chip and a memory chip may be mentioned in the same sentence, it should not be construed that they are equivalent structures.

FIG. 1 is a schematic 100 that includes an article according to an example embodiment. A hardware resource 110 such as a microprocessor is coupled to a mounting substrate 112. In an embodiment, the hardware resource 110 is a microprocessor made by Intel Corporation such as an Atom®, or a Celeron®, or a Core®. In an embodiment, the hardware resource 110 is a system-on-chip (SOC) that includes processing and other capabilities such as for a smart phone. In an embodiment, the hardware resource 110 is a memory chip or a memory module. In an embodiment, the hardware resource 110 is a chipset or an element of a chipset.

An RFID tag 114 is also disposed on the mounting substrate 112, and it is coupled to the hardware resource 110 by a serial bus 116 according to an embodiment. In an embodiment, the RFID tag is formed in a semiconductive substrate. The RFID tag 114 uses an RFID antenna 118 such as a copper loop 118. In an embodiment, the RFID antenna is a dipole structure that is tuned for the specific application.

-2The RFID antenna 118 is depicted as a loop on the mounting substrate 112 in this embodiment. In an embodiment, the RFID antenna is located on a motherboard where the mounting substrate 112 is a component package disposed on the mother board. In an embodiment, the RFID antenna is located on a chassis where the mounting substrate is a component package coupled to a larger substrate. In an embodiment, the RFID antenna is integrated into the shell of the system into which the RFID tag is installed. For example, a smart phone outer shell has the RFID antenna molded as an integral part of the shell.

In an embodiment, the RFID tag 114 carries a unique identifier that is related to the specific hardware resource 110. The RFID tag 114 also stores data related to the synergy of the hardware resource 110 and the mounting substrate 112.

The RFID tag 114, serial bus 116, and RFID antenna 118 may be referred to as a radio-frequency (RF) communication capability for the hardware resource 110. In an embodiment, however, the RF communication capability is disposed integral with the hardware resource (“in the silicon”) such that the functionalities of at least the RFID tag 114 and serial bus 116 are integrated in the semiconductive material of the hardware resource 110.

An antenna 120 such as a dongle with firmware is coupled to a RFID reader device that is coupled to a computing system 122 and the computing system 122 is coupled to a secure database 124. The computing system 122 is depicted as a generic desktop computer but it may be any suitable computing system that is not hard-wired to the hardware resource 110. In an embodiment, the hardware resource 110 is authenticated with the secure database 124 through the RFID tag 114 by allowing the computing system 120 to query 110 and issue a license to the RFID tag 114 which has a unique encrypted identifier. The secure database 124 (also referred to as a remote server 124) issues a license that is written by RF communication to the hardware resource 110 or another component in the system.

In an embodiment, the hardware resource 110 is used as a secure source of reconfiguring any or all other components in a system by use of communication through the RFID tag 114 to the secure database 124. For example, a solid-state drive is reconfigured or up- or down-binned though use of the hardware resource 110. In an example embodiment, memory usage is reconfigured or up- or down-binned through use of the hardware resource 110. In an example embodiment, software is reconfigured such as up- or down-graded through use of the hardware resource 110. In an example

-3embodiment, firmware is reconfigured or up- or down-binned through use of the hardware resource 110.

Unit-level traceability (ULT) data with respect to the hardware resource 110 and the mounting substrate 112 and tag 114 are cached on the tag 114 and also stored at the secure database 124. The ULT data is stored as a copy in a secure database 124 with a business entity that is associated with the manufacturing genealogy of the hardware resource 110. In some embodiments, the secure database 124 is located remotely from the hardware resource 110. In any event, “remote database” refers herein to a secure database that may or may not be located remotely from the given hardware resource(s).

Manufacturing genealogy includes several of the conditions of processing and assembly of the hardware resource 110 and the mounting substrate 112, although they may each be manufactured by a different entity.

The ULT data may be related to each of the hardware resource 110 and the mounting substrate 112, as well as the RFID tag 114. In an embodiment, a ULT datum includes date of manufacture. In an embodiment, a ULT datum includes the location of manufacture, also referred to as “fab” and may include a subdivision process used in the fab. In an embodiment, a ULT datum includes process equipment used in the manufacture such as tracking data of etch tool(s), spin-on tools, and thermal treatment tools to mention a few. In an embodiment, a ULT datum includes a specific process flow as process flow can be complicated and composed of dozens of sub-process flows. In an embodiment, a ULT datum includes the wafer-site origin of the hardware resource 110 where process variation may occur on a single wafer before singulation of the wafer into several hardware resources. Wafer-site origin data may track, for example, a particularly highyielding sector on a wafer that is related to a portion of a stepper used in the process. Other manufacture data may be encrypted and cached on the RFID tag 114 and simultaneously at the secure database 124.

In an embodiment, clock speed of the hardware resource 110 is recorded such as at a bin-splitting test location. Clock speed may be variable due to down-binning requirements dictated in the marketplace, and the hardware resource 110 may be set to operate at less than 100 percent of the maximum clock speed. Consequently, the hardware resource 110 may be bin-split to a bin that is designated with a slower clock speed than the maximum capability due to marketing and sales conditions for the specific hardware resource 110.

-4Power consumption is a performance parameter that may also be encrypted and cached on the RFID tag 114 and in the secure database 124. Similar bin-split methods may be carried out where a given hardware resource 110 consumes less power than others, but market conditions do not require the lowest power configuration.

Cache size is a performance parameter that may also be encrypted and cached on the RFID tag 114 and in the secure database 124. Similar bin-split methods may be carried out where a given hardware resource 110 requires less cache than what has been fabricated and verified, but a given application does not require the total cache that was achieved.

A maximum-efficiency instruction set is a performance parameter that may also be encrypted and cached on the RFID tag 114 and in the secure database 124. Similar binsplit methods may be carried out where a given hardware resource 110 required less than the maximum-efficiency instruction set, or even an instruction set that does not need all features in the total instruction set.

The mounting substrate 112 may also have ULT data associated with it to assist in matching a given hardware resource 110 that has been mated with a given mounting substrate 112. Similar bin-splitting data for the mounting substrate 112 may be recorded. Other ULT data that can be securely stored includes field-collected data such as if delamination occurs between a mounting substrate 112 and the hardware resource 110.

Because of positive and negative synergistic effects between a given hardware resource 110 that has been mated with a given mounting substrate 112, ULT data for the mounting substrate 112 may play a role in several method embodiments disclosed herein. For example, a first mounting substrate supplied from a first supplier may create synergistic-performance characteristics when mated with a given hardware resource that a second mounting substrate supplied from a second supplier does not. In any event, ULT data is recorded with the secure database 124 for a given hardware resource 110 mated to a given mounting substrate 112.

The schematic 100 illustrates a method where a determination is made whether a system is compatible with a specific upgrade to the hardware resource 110. The system may include the hardware resource 110 alone or it may include the mounting substrate 112 and even other components that may be coupled to the hardware resource 110 and the mounting substrate 112. The hardware resource is communicated to by RF with the

-5antenna 120 signaling 121 and the hardware resource 110 answering 115 through the RFID tag 114.

In an embodiment, the RFID tag 114 is entirely passive but it has the capability along with the RFID antenna 118 to communicate with the hardware resource 110 and reconfigure a performance characteristic, e.g., the clock speed. In an embodiment, the RFID tag 114 requires external assistance to re-program the hardware resource 110 such as it uses an external battery but the RF communications suffice for all logic-driven instructions to re-program the hardware resource 110. In an embodiment where the hardware resource 110 is installed into a system, power to reconfigure the system is taken from the system through the serial bus 116 such as 2-pin DC power.

In an embodiment, an upgrade is a recent software-firmware like microcode version that updates current software firmware-microcode previously intended for use by the hardware resource 110. In an embodiment, an upgrade is a new configuration-setting to support a software application that the hardware resource 110 has capability to process, but that was not commercially available at the time the hardware resource 110 was sold or offered for sale. In an embodiment, an upgrade is a new software application that the hardware resource 110 has capability to process, but that was not bundled with the hardware resource 110 at the time the hardware resource 110 was sold or offered for sale.

In an embodiment, the RF programming accomplishes unleashing a second capability the hardware resource 110 that is enhanced compared to the first capability of the hardware resource 110 prior to the communication to the secure database 124.

In an embodiment, RF programming of the hardware resource 110 is accomplished by the RFID tag 114 without any external power requirement except from the antenna 120. Consequently, RF programming can be accomplished by the RFID tag 114 even after the hardware resource 110 has been packaged for shipping such that line-of sight data may be obscured. As a result, both identification of the hardware resource 110 as to ULT data and performance data, and programming of the hardware resource 110 may be carried out without the need for external power pins such as from a plugged-in system.

In an embodiment, a system such as that containing the hardware resource 110 may be determined if it is compatible with an upgrade by identifying and validating the RFID tag 114 as having a unique, qualified identification. If the system is compatible, a method embodiment includes authenticating the hardware resource 110 with the remote database 124 by communicating with the RFID tag 114. Where the hardware resource 110 -6is commercially packaged, line-of sight identification is not necessary since the RFID tag 114 is capable of affirming whether the system is capable of an upgrade to the hardware resource 110. Consequently, RF instructions are received at the RFID tag 114 from a remote system such as the computing system 122, and line-of sight identifiers such as twodimensional (2D) laser inscriptions are not needed.

In an embodiment, the hardware resource 110 has been down-binned and it has been sent to a potential vendor as a demonstration sample. Before the hardware resource 110 is sent, it is programmed with a trial counter to track a given number of times it is booted such that after the given number of times, it locks and cannot be used further or metered (meaning reboot a specified every n minutes) at the given binning level without receiving a renewal license from the secure database 124. Another method of tracking usage is total time the hardware resource is in operational mode, followed by one of upbinning, down-binning or locking the hardware resource. In an embodiment, after the agreed-to amount of use of the demonstration sample has been reached, the hardware resource reverts to an original configuration. According to an embodiment, the programming such as up or down-binning after agreed use may be done by permanently burning a fuse in the control logic post authentication of the license in the tag 114 by the hardware resource 110.

In an embodiment, after the given number of boots has occurred, the hardware automatically up-bins or down-bins and the potential vendor is notified. As a consequence of this embodiment, the potential vendor is sent fewer samples due to the ability of the hardware resource to do one of up-binning and down-binning such that a single demonstration sample is used in place of several otherwise. In an embodiment, the result of up-binning or down-binning and notification is that the potential vendor may receive a license to continue, or to purchase the hardware resource sample.

Programming and reconfiguring of the hardware resource 110 may be carried out at several locations and during the several phases of fabrication, assembly, test, shipping, pre-sale, and post-sale among other events.

Fab-Stage Programming

Fab-stage programming may also include assembly and test-stage programming. In an embodiment, the shipment lot has been packaged and transferred to assembly and test. Upon arrival at assembly and test, the shipment is RF-surveyed through each RFID tag.

-7In an embodiment during assembly and test, it becomes clear the hardware resource 110 is performing significantly below expectation. Consequently, the specific hardware resource 110 is recalled for containment. In an embodiment during assembly and test, it becomes clear the hardware resource 110 is performing significantly above expectation. Consequently, the specific hardware resource 110 is recalled for further study and commonality analysis to fine-tune the fabrication processes.

Once a hardware resource 110 has been mated with a given mounting substrate 112 and tested, the ULT data for the hardware resource 110 is rewritten as ULT-2 data that encompasses the synergy of the hardware resource 110 and the mounting substrate 112 and the unique ID of the tag 114. The ULT-2 data is recorded with the secure database 124. To avoid the time-consuming actions of socketing and programming the hardware resource 110, RF programming is carried out in mass or singulation as desired. In an example embodiment, a clock speed of 2.0 GHz is needed for a given hardware resource 110, but the hardware resource 110 operates at 2.4 GHz when mated to the given mounting substrate 112. The hardware resource is communicated to by RF with the antenna 120 signaling 121 and the hardware resource 110 answering 115. The RF programming in this embodiment includes re-fusing the hardware resource 110 to be down-binned from 2.4 GHz to 2.0 GHz as required in filling a contract for sale. The event of down-binning is recorded with the secure database 124 through the RFID tag 114.

Warehouse-Stage programming

Warehouse-stage programming may be carried out as early as arrival at a given warehouse. In an embodiment, a shipment lot of hardware resources, each including RFID tags with access to a secure database, is received and an RF-based survey of the shipment is carried out to authenticate each unit in the shipment has arrived where it was intended.

FIG. 2a is a schematic 200 of a method according to an embodiment. An array of hardware resources is depicted disposed upon mounting substrates, one hardware resource of which is indicated with reference numeral 210. The array is depicted as 12 hardware resources and a 2x6 table is located adjacent the array to represent respective ULT and performance registers, one of which corresponds to the indicated hardware resource 210 with the reference numeral 211. The indicated hardware resource 210 has been bin-split with a 2.4 GHz clock speed as a non-limiting embodiment. Bin-splitting may also be done

-8based upon a processing-genealogy parameter that has had useful history correlated to device outcome.

In FIG. 2a, an antenna 220 is being used to communicate simultaneously to all 12 hardware resources 210. In an embodiment, the 12 hardware resources 210 are located in a post-production warehouse and they have been processed, assembled with respective mounting substrates, tested, bin-split, and configured as a shipment lot. Simultaneous communication between a secure database and all of the hardware resources through their respective RFID tags is done by multiplex (MUX) communication. In an embodiment, MUX communication may cause communication to focus on a given hardware resource such that batch communication is accomplished.

Initial best-performance data was established by querying performance parameters and recording them with the secure database. A first sub-array 226a has been bin-split to have a clock speed of 2.4 GHz (eight units), a second sub-array 228a has been bin-split to have a clock speed of 2.0 GHz (two units), and a third sub-array has been bin-split to have a clock speed of 1.8 GHz (two units). Other performance parameters may be a cause for different bin splitting, and complex bin splitting may include a first bin split for clock speed but a lower than first bin split for some other parameter such as power consumption or a process condition.

The antenna 220 is connected to a computing system such as the computing system 122 depicted in FIG. 1, and the computing system is also in communication with a remote data base such as the secure data base 124 also depicted in FIG. 1. It should be understood that RFID tag 214, although depicted as a component separate from the hardware resource 210, may be integral to the hardware resource according to an embodiment.

In an embodiment, the 12-unit array of hardware resources 210 is in a warehouse that is remote from the secure data base, and remote communication between the hardware resources 210 to the secure database is used to authenticate each component and to determine if any of the systems is compatible with an upgrade.

In an embodiment, an RF survey for extant 2.4 GHz hardware resources is done by communicating to each RFID tag. Each hardware resource in the sub-array 226a answers in the affirmative, but each hardware resource in the sub-arrays 226b and 226c answers in the negative. This method embodiment may be carried out when a specific quality of hardware resource is needed and a warehouse lot is RF surveyed to match qualified hardware resources a given software or application. In these embodiment, the first

-9programming depicted in FIG. 2a may be referred to as first programming, whereas a repeated programming as depicted in FIGs. 2b and 2c may be referred to as “second programming”, “subsequent programming” or the like.

Shipment-Stage Programming

FIG. 2b is a schematic 201 of the method depicted in FIG. 2a after further events according to a method embodiment. In a method embodiment, a purchaser has ordered 12 units, but market parameters dictate the need for only two of the systems in the 12-unit array (FIG. 2a) to have the 2.4 GHz clock speed. Consequently, six of the hardware resources in the first sub-array 226a that had a maximum 2.4 GHz clock speed, were down-binned by communication through the respective RFID tags because their maximum clock speeds are not needed by the purchaser. Consequently, the hardware resource 210, although it was evaluated at a 2.4 GHz clock speed 211 as depicted in FIG. 2a, has been down-binned to a 2.0 GHz clock speed by communication through the respective RFID tags as depicted in FIG. 2b. Similarly, the purchaser order included four units with a clock speed of 1.8 GHz, such that two of the units depicted in FIG. 2a that had a clock speed of 2.0 GHz have been down-binned to clock speeds of 1.8 GHz.

In the process of down-binning, the down-binning event is accomplished by RF programming such that the 12-unit array can be programmed by communication through the respective RFID tags without the need for line-of-sight identification. This scenario may occur where the array has already been packaged such that each system has been visually obscured. Similarly in the process of down-binning, the down-binning event is simultaneously (or at least parallel-processing) accomplished by RF programming instead of the much slower seriatim processing by physically plugging each unit into a programming socket.

In an embodiment, the 12-unit array is down-binned as depicted in FIG. 2b and the array is shipped as a commercial lot. Before shipping according to an embodiment, each unit is also locked through RF programming such that only the recognition and authentication of each unique encrypted identifier in each RFID tag will allow unlocking once received by the authorized purchaser. In an embodiment, a shipment lot is lost, misdirected, or stolen. Because each hardware resource in the lot is locked and has an encrypted unique identifier accessible through the individual RFID tag, however, activation of each hardware resource will be difficult if not impossible. This is because

-10each hardware resource identification and authentication from a secure database communicated through each respective RFID tag.

Where the purchaser is an original equipment manufacturer (OEM) for example, the OEM is recorded on each RFID tag and each hardware resource is disabled such as by locking before shipping. For purposes of this disclosure, an “OEM” may also refer to a post-sale entity that further operates on the hardware resource-containing system, and may or may not sell it to the public. Upon delivery to the OEM, a method embodiment allows the OEM to determine if each hardware resource was intended for the OEM. If the hardware resource was so intended, the OEM is allowed to unlock the hardware resource for further assembly by communicating to each unit by the respective RFID tag.

Point-of-Sale Programming

FIG. 2c is a schematic 202 of the embodiment depicted in FIG. 2b after further events according to an embodiment. Where a purchaser has received the 12-unit lot, an antenna 220 (and accompanying computing system) are used to allow the OEM to determine if a given hardware resource in the lot was intended for the OEM. This is accomplished by querying each hardware resource in the lot by RF polling through the several RFID tags in the lot and recognizing each unique encrypted identifier that is cached in the accompanying RFID tag.

In an embodiment where a given hardware resource in the lot has been misdelivered, the identification and authentication fails, the hardware resource remains locked, and it is imperative that it be returned to the manufacturer.

In an embodiment, a contract for sale or evaluation is established with an OEM based upon market parameters and the down-binning event illustrated between FIG. 2a and FIG. 2b has been achieved.

Before further processing of the hardware resource lot, a change in at least one market parameter is observed. The change in the market parameter may be a marketing technique according to an embodiment, where the supplier makes an offer to up-bin some or all of the systems for a given discount. The change in the market parameter may be a changed sales expectation by the OEM such as different hardware resource capability needs have been observed, compared to a previous marketing forecast. The change in the market parameter may be a software application upgrade has come on the market that may take advantage of more up-binned hardware resources according to an embodiment. The change in the market parameter may be a new software application has come on the

-11market that may take advantage of more up-binned hardware resources according to an embodiment. The change in the market parameter may be an upgraded chipset application has come on the market that may take advantage of more up-binned hardware resources according to an embodiment. The change in the market parameter may be an entirely new chipset configuration has come on the market that may take advantage of more up-binned hardware resources according to an embodiment.

In any event, upon observing at least one change in the market parameters, the OEM communicates with the secure database and makes an offer for one of down-binning or up-binning to modify the contract.

FIG. 2c represents an example embodiment of such a response to a change in at least one market parameter. Where only two hardware resources were configured at 2.4 GHz at 226b in FIG. 2b, a net of four hardware resources have been enabled at this clock speed at 226c by the OEM receiving a new license. Where six hardware resources were configured at 2.0 GHz at 228b, a net of five hardware resources have been enabled at this clock speed at 228c. And where four hardware resources were configured at 1.8 GHz at 230b, a net of three hardware resources have been enabled at this clock speed at 230c.

Reference is again made to FIG. 1. In a first example embodiment, the hardware resource 110 is part of a system that is being point-of-sale removed from a commercial vendor. At the cash register or some appropriate location within the commercial vendor’s control, the purchaser is notified that the system can be upgraded for a given price to unleash a second capability in the hardware resource 110 that is enhanced from the current configuration. Where the purchaser agrees to the offer, an RF dongle 120 is used to communicate to the hardware resource 110 through the RFID tag 114. By RF communication, it is determined that the system is compatible with an upgrade. This is accomplished by accessing the remote database 124 telephonically where the remote database is located off-site from the point-of-sale location. The hardware resource 110 is authenticated with the remote database 124, a license is granted between the owner of the remote database 124 and the purchaser, and the hardware resource 110 receives the license by use of the serial bus 116 when powered and authenticates the license that was stored in the RFID tag 114 to upgrade the hardware resource 110. Thereby programming is accomplished based upon the RF instructions without even removing the hardware resource 110 from its commercial packaging. Consequently in an embodiment, the RF

-12programming is accomplished without powering up the hardware resource 110 from a hard-line power source including internal batteries.

In a second example embodiment, the same method is used as in the first example embodiment, except the system awakens the internal batteries to power up the hardware resource 110 and unleash a second capability.

In a third example embodiment, the same method is used as in the first example embodiment, except the upgrade is offered and accepted for a limited time.

In an embodiment, an issue arises with a given hardware resource 110 such as performance anomalies. Where the, e.g. performance anomaly is a sub-standard event, the specific hardware resource 110 may be requested for recall to remove it for study to determine if the sub-standard event may be repaired for this given hardware resource 110, or for similar hardware resources.

Where the, e.g. performance anomaly exceeds the standard in a surprising, positive manner, the specific hardware resource 110 may be requested for recall to remove it for study to determine how the above-standard behavior may be replicated for similar hardware resources or for future production.

Post Point-of-Sale Programming

In an example embodiment, a hardware resource that is contained in a smart phone has been in use after a point-of-sale event, and software has finally become available that can take advantage of more capability in the hardware resource. In this embodiment, a hardware resource disposed in the smart phone has been down-binned and a time period has passed during which time software upgrades or new software has been developed that can take advantage of the hardware resource in an up-binned reconfiguration. Where the down-binning at the warehouse or at assembly and test may be referred to as first programming, a repeated programming such as this up-binning embodiment may be referred to as subsequent programming.

For example, new software has been developed, and the software is correlated to a shipment lot of hardware resources that was previously sold to an OEM. The user may take the hardware resource to an authorized vendor for up-binning. Where authentication of the RFID tag 114 is true, ULT and performance data related to the hardware resource are shared with the secure database. If reconfiguring of the hardware resource 110 is allowable, programming is carried out by sending and receiving RF instructions through the RFID tag.

-13As a consequence of the programming, the ULT data is updated which means the specific programming is recorded as an event not only related to the synergy of the hardware resource and the mounting substrate, but it is also recorded with and the secure database.

FIG. 3 is a cross-section elevation of a mounting substrate 300 according to an example embodiment. The mounting substrate 300 includes a core 312 and an RF antenna 318 embedded in several layers including interlayer dielectric material 332. The RF antenna 318 is disposed in a keep-out zone (KOZ) 334. In the illustrated embodiment, the KOZ 334 has a 250 micrometer (pm) buffer at the edge and a 150 pm buffer opposite the edge and adjacent the RF antenna 318. In an embodiment, the RF antenna 318 is 250 pm as illustrated. In an embodiment, the RF antenna 318 is about 200 pm thick in the Zdimension.

Several metallization layers are depicted at 336, 338, 340, 342, and 344 according to an embodiment. A solder mask 346 is also depicted against the mounting substrate at the upper surface.

In an embodiment, an RFID tag 314 is located on the solder mask 346 and electrical communication to the RF antenna 318 is coupled though the any or all of the several metallization layers. Similarly, a hardware resource 310 is also disposed on the mounting substrate 300 on the solder mask 346 upper surface.

In an embodiment, the RFID tag is to be located inside the mounting substrate 300 such as taking up some of the space occupied by the core 312. Consequently, the RFID tag (part of the core space 312) and the RF antenna are integral to inner structures of the mounting substrate 300. Similar structure are reflected in the negative-Z direction starting at the core 312.

FIG. 4 is a flow diagram of a method 400 according to an example embodiment. A method 400 is used to up-bin or down-bin a hardware resource of a target system.

At 405, the method 400 includes RF communicating with a target system by use of the RFID tag contained in the system. For example, a remote server of an OEM, reseller, or the like communicates with the target system by querying the RFID tag that is coupled to the hardware resource. In various embodiments, the communication may be transparent to a user of the system. In an embodiment, the remote server requests information regarding a configuration of the target system so that a determination may be made as to

-14whether the hardware resource of the target system is able to be up-binned or downbinned.

At 410, the target system is certified for an up-bin or down-bin. In various embodiments, information in a supported configuration ULT table is communicated to the remote server upon a request by the remote server. This communication between the remote server and the target system may also be transparent to an end user. The remote server determines that the target system is not certified for an up-bin or down-bin. If it is not certified, the method 400 is terminated.

At 415, if the target system is certified for an up-bin or down-bin, next it may be determined whether the recipient of the hardware resource desires to up-bin or down-bin the system. While various manners of determining whether a system is desired to be upbinned or down-binned may exist, in many embodiments a message from the remote server to the target system may be sent. The message may be caused to be displayed on the target system, for example, by a pop-up or other message block to indicate availability of the up-bin or down-bin. If the recipient of the hardware resource does not desire the up-bin or down-bin, the method 400 is terminated.

At 420, if instead a holder of a hardware resource desires the up-bin or down-bin, the target system may get an encrypted license from the remote server. In various embodiments, the encryption key is a unique code that identifies the target system and/or a particular hardware resource of the system, e.g., a processor or chipset. When the encryption key is sent, the remote server accesses the unique ULT record for the given hardware resource.

The remote server uses the encrypted key to generate encrypted instructions that enable the up-bin or down-bin. For example, the remote server generates microcode instructions and optionally encrypts the instructions to prevent unauthorized access to the instructions. The microcode instructions are used by the target system to appropriately program one or more hardware components to enable the feature(s) for operation. The remote system also generates validation instructions for transmission to the target system to confirm that the up-bin or down-bin was successful and that the target system can perform code that implements the desired feature.

At 425, the remote server accordingly transmits encrypted up-bin or down-bin instructions to the target system.

-15At 430, the target system decrypts the up-bin or down-bin instructions with the decryption key corresponding to the encrypted instructions, and it programs the target system. In a non-limiting example embodiment, decrypted microcode instructions are used to securely allow up-binning or down-binning to occur with less concern for security breaches. In other words, microcode instructions are decrypted and sent directly to a processor core, where the microcode instructions are executed internally to initiate programming. Because the transmitted instructions may be in microcode in these embodiments, the ability of unauthorized extraction of the instructions or to provide the instructions to unauthorized parties is significantly reduced.

In some embodiments, the microcode instructions are executed by the processor to initiate the programming of the feature(s) to be upgraded. For example, in some embodiments the microcode instructions initiate dynamic fuse programming logic within a processor or other hardware component to open one or more fuses to enable a path to circuitry previously unavailable. In these embodiments, the dynamic fuse programming logic may cause a source voltage to be provided to a fuse bank or the like to cause the selected fuses to be enabled. Upon successful enabling of a fuse, a path is made to circuitry that performs the feature.

At 435 it is determined whether the up-bin or down-bin was successful after programming the component to enable the feature. In various embodiments, code transmitted by the remote server may be used to verify operation of the enabled feature. For example in an embodiment, validation code is sent with the microcode instructions. Upon completion of the programming, the target system executes the validation code. The validation code may exercise the newly enabled circuitry to verify that it operates for its intended purpose, and more specifically to verify that it operates in the specific configuration of the target system.

At 435, where it is determined the up-bin or down-bin was not successful, control passes to block 440 where an error handling procedure is performed. In various embodiments, error handling code may be implemented on the target system to handle the error. In some embodiments, the error handling procedure may be downloaded from the remote source. At 445, after the error handling code is performed, it is determined whether to retry the up-bin or down-bin process. For example, if the error handling routine corrected the error, the up-bin or down-bin process may be reattempted. If the upbin or down-bin is to be retried, control returns to block 430.

-16If instead at 435 it is determined that the up-bin or down-bin was successful, the up-bin or down-bin is reported to the remote server at 450. Specifically, information from the supported configuration ULT table is sent to the remote server to indicate successful completion of the up-bin or down-bin. In addition to the information from the supported configuration table, information identifying the target system may be included so that the remote server can take appropriate measures.

At 460 in an example embodiment, the remote server charges an account associated with the target system for the up-bin or down-bin. For example, an IT department of an enterprise maintains an account with the OEM that implements the remote server. In an embodiment, different measures of paying for upgrades are used. For example in an embodiment, an individual end user may provide credit card information to authorize billing charges for an up-bin or down-bin desired by the end user.

In addition to receiving payment for the up-binning or down-binning, the remote server may store information regarding the up-bin or down-bin including, for example, information regarding the identification of the target system, the upgrades effected, and additional information about the target system, such as platform, build, image, and the like. Further, as shown in FIG. 4 at 470, the remote server communicates the up-bin or down-bin information to a central database.
