SEMICONDUCTOR DEVICE AND METHOD OF CONTROLLING SEMICONDUCTOR DEVICE

PROBLEM TO BE SOLVED: To provide a semiconductor device using a variable resistive element that does not pass current more than required and completes a write operation in an appropriate number of times.SOLUTION: A semiconductor device includes: a variable resistive element and a control circuit that controls the resistance state of the variable resistive element by controlling current between one end and the other end of the variable resistive element. The control circuit causes a first current to flow from the one end of the variable resistive element to the other end so as to change the variable resistive element from a first resistance state to a second resistance state. In addition, the control circuit causes a third current to flow from the other end to the one end after causing a second current smaller than the first current to flow from the one end to the other end of the variable resistive element, so as to change the variable resistive element from the second resistance state to the first resistance state.
