Address multiplexing in pseudo-dual port memory
Abstract
one. Pseudo-dual-port memory address multiplexing system, containing:! read port address trigger designed to store the read address in response to an external synchronization signal; ! trigger of the recording port address, designed to store the recording address in response to an external synchronization signal; ! control circuit which controls read / write access to memory, based on the control of the first memory access operation; and! multiplexer which switches between the stored read address and the stored write address in response to the switching signal from the control circuit. ! 2. The pseudo-dual-port memory address multiplexing system of claim 1, wherein the first memory access operation is a memory read operation. ! 3. The pseudo-dual-port memory address multiplexing system according to claim 2, wherein the read port address trigger is released after the read operation. ! four. The pseudo-dual-port memory address multiplexing system according to claim 3, wherein the write address trigger remains in a locked state after a read operation. ! five. The pseudo-dual-port memory address multiplexing system according to claim 4, wherein the write port address is freed after the write operation. ! 6. The pseudo-two-port memory address multiplexing system according to claim 1, wherein the control circuit comprises an internal synchronization delay circuit that generates an internal synchronization delay, the control circuit setting the level of the internal synchronization signal after the internal synchronization delay to start the second memory access operation. ! 7. Multiplexing System
