Patent ID: 8848433

Claim:
A nonvolatile memory device, comprising: a magnetic memory element including a stacked body, the stacked body including a first stacked unit including: a first ferromagnetic layer having a fixed direction of magnetization; a second ferromagnetic layer having a changeable direction of magnetization; and a first nonmagnetic layer provided between the first ferromagnetic layer and the second ferromagnetic layer, the first ferromagnetic layer, the second ferromagnetic layer, and the first nonmagnetic layer being stacked in a stacking direction, and a second stacked unit stacked with the first stacked unit in the stacking direction including: a third ferromagnetic layer having a changeable direction of magnetization; and a nonmagnetic tunneling barrier layer stacked with the third ferromagnetic layer in the stacking direction to contact the third ferromagnetic layer; and a control unit electrically connected to the magnetic memory element, the control unit being configured to implement a first operation of setting the magnetic memory element to be in a first state, the first operation including: a first preliminary operation of applying a first pulse voltage having a first rising time to the magnetic memory element; and a first setting operation of applying a second pulse voltage having a second rising time to the magnetic memory element after the first preliminary operation, the second rising time being longer than the first rising time.
