Patent ID: 8331136

Claim:
A recording method of a nonvolatile memory including a recording circuit that electrically performs recording of information for an information memory device having a resistance change connected to a power supply for information recording, the method comprising the steps of: recording information in a low-resistance state by the recording circuit under a condition that an output impedance of the recording circuit for the information memory device is larger than a resistance value in the low-resistance state of the information memory device; and recording information in a high-resistance state by the recording circuit under a condition that an output impedance of the recording circuit for the information memory device is smaller than a resistance value in the high-resistance state of the information memory device, and wherein, when the information in the low-resistance state is recorded, control of the recording is performed by current control, and, when the information in the high-resistance state is recorded, control of the recording is performed by voltage control.
