DRIVING METHOD OF NANOGAP DEVICE AND STORAGE DEVICE EQUIPPED WITH NANOGAP DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a driving method of a nanogap device and a storage device equipped with the nanogap device, capable of appropriately storing multivalued information on three or more values in the nanogap device.

SOLUTION: The nanogap device 10 is arranged between a first electrode 2 and a second electrode 3 provided on an insulating substrate 1 and provided with an inter-electrode gap part 4 having a gap of a nanometer order and resistance states to be switched by application of a predetermined voltage between the first electrode 2 and the second electrode 3, and the resistance states are divided as three or more states. It is configured such that a voltage pulse of a voltage value corresponding to each resistance state is applied between the first electrode 2 and the second electrode 3 of the nanogap device 10, and when one or more other resistance states exist between the resistance state before application which is the present resistance state, and the objective resistance state, a voltage pulse of a voltage value corresponding to the objective resistance state is applied after a voltage pulse of a voltage value corresponding to the other resistance state is applied in the order of the magnitude of the voltage value.
