A method of driving a device having a pair of electrodes and organic insulating layer sandwiched therebetween. The device exhibits at least three states of different electroconductivities in response to an applied voltage. A transition from the first state to the second state is achieved by applying a voltage within a first predetermined range to the device in the first state, and a transition from the second state to the third state is achieved by applying a voltage within a second predetermined range to the device in the second state.
