Abstract:
According to one embodiment, a semiconductor memory device includes a first electrode, a second electrode, a memory cell, and a control circuit. The memory cell is provided between the first electrode and the second electrode, and includes a metal film and a resistance change film. The control circuit applies a voltage between the first electrode and the second electrode to transition a resistive state of the memory cell. The control circuit performs a first reset operation by applying a first pulse having a voltage of a first polarity to the memory cell, and applying a second pulse having a voltage of a second polarity that is an inverse of the first polarity to the memory cell after applying the first pulse.
