Abstract
A semiconductor device is provided with the variable resistance element, and a control circuit that controls a resistance state of the variable resistance element by controlling current between a first end and a second end of the variable resistance element. The control circuit causes the variable resistance element to change from a first resistance state to a second resistance state by having a first current flow from the first end to the second end of the variable resistance element. In addition, after a second current smaller than the first current is made to flow from the first end to the second end of the variable resistance element, the control circuit causes the variable resistance element to change from the second resistance state to the first resistance state by having a third current flow from the second end to the first end thereof.
