Abstract

According to one embodiment, a magnetoresistive memory device includes: a first conductor; a layer stack; an insulator on a side surface of the layer stack; a second conductor on a second surface of the layer stack; a third conductor; and a fourth conductor on the third conductor. The layer stack includes a first ferromagnetic layer, a second ferromagnetic layer, and an insulating layer between the first ferromagnetic layer and the second ferromagnetic layer and has a first surface in contact with the first conductor. The second surface is at an opposite side of the first surface. The third conductor has a portion on the second conductor and a portion on a side surface of the insulator.
