Abstract
A storage device includes a first conductive layer, a second conductive layer, a first variable resistance layer, and a control circuit. The control circuit is configured to apply a first voltage between the first conductive layer and the second conductive layer for a first time and apply a second voltage less than the first voltage for a second time longer than the first time after the application of the first voltage when the first variable resistance layer is in a first high resistance state. The control circuit is further configured to apply the first voltage between the first conductive layer and the second conductive layer and apply a third voltage less than the second voltage between the first conductive layer and the second conductive layer after the application of the first voltage when the first variable resistance layer is in a first low resistance state.
