Memory cell, memory using the memory cell, memory cell manufacturing method, and memory recording/reading method

Conventional memory is completely different from the construction, and provides a number of properties and excellent memory cell and its manufacturing method. Further, by using the memory cell a number of the characteristics provides an excellent memory. It also provides a write / read method of the memory. And a memory medium for holding information, a control unit for recording information in the memory medium, for reading information from the memory medium includes a detecting element, the detection element which is independent from the memory cell in the memory medium. More specifically, for example, and the memory medium is a magnetic body, wherein the control unit includes a generating a first magnetic field for changing the magnetization state of the magnetic material by applying a magnetic field to the magnetic material, the detection device is the vicinity of the magnetic material It is disposed, and also a memory cell including an electrical property different from the rotation conversion in accordance with the magnetization state of the magnetic material.
