According to one embodiment, a resistance-change memory includes a memory element in which its variable resistance state corresponds to data to be stored therein, a pulse generation circuit which generates a first pulse, a second pulse, a third pulse, and a fourth pulse, the first pulse having a first amplitude which changes the resistance state of the memory element from a high- to a low-resistance state, the third pulse having a third amplitude smaller than the first amplitude to read data in the memory element, the fourth pulse having a fourth amplitude between the first amplitude and the third amplitude, and a control circuit which controls the operations of the memory element and the pulse generation circuit. The control circuit supplies the fourth pulse to the memory element after supplying the first pulse to the memory element.
