RECORDING METHOD OF NONVOLATILE MEMORY, AND NONVOLATILE MEMORY

摘要

PROBLEM TO BE SOLVED: To achieve long life and highly reliable recording by suppressing destruction of an information memory element or shortage of the life caused by the recording, in a nonvolatile memory for recording a resistance change as information.SOLUTION: The recording method of the nonvolatile memory includes a recording circuit which electrically performs recording of information for the information memory element having a resistance change. In the recording circuit, the information in a the low-resistance state is recorded in a state where an output impedance of the recording circuit for the information memory element is larger than a resistance value in the low-resistance state of the information memory element, and also in the recording circuit, the information in a high-resistance state is recorded in a state where an output impedance of the recording circuit for the information memory element is smaller than a resistance value in the high-resistance state of the information memory element.
