Abstract
In a drive method that enables more stable switching operations, a memory element (10) is equipped with an insulating substrate (1) provided with a first electrode (2), a second electrode (3), and an electrode gap portion (4) for generating a resistance change phenomenon between the first electrode and the second electrode. By applying to the memory element a first voltage pulse from a pulse generation source for shifting the memory element from a predetermined low resistance status to a predetermined high resistance status, and a second voltage pulse for shifting from the high resistance status to the low resistance status via a serially connected resistor, the current flowing to the memory element after the change to the low resistance value is reduced. The drive method is characterised in that the voltage pulse is applied so that the electrical resistance between the memory elements from the pulse generation source is higher when shifting from the high resistance status to the low resistance status, than when shifting from the low resistance status to the high resistance status.

Abstract
In order to carry out switching operations with greater stability this drive method for a memory element (10) is characterised by applying current pulses to the memory element, by means of a constant current circuit, when switching from a high resistance state to a low resistance state. The memory element (10) is provided with: an insulating substrate (1); a first electrode (2) and a second electrode (3), which are provided on the insulating substrate; and an inter-electrode gap unit (4) which is provided between the first electrode and the second electrode, and which has nanometre-order gaps wherein a change in the resistance between the first and the second electrodes occurs. The memory element is capable of switching from a prescribed low resistance state to a prescribed high resistance state, and from a high resistance state to a low resistance state.
