According to one embodiment, a plurality of first wirings is disposed in first and second directions crossing each other and extends in a third direction perpendicular to the first and second directions. Second wirings extend in the second direction and are provided at a predetermined interval in the third direction of the first wirings. The first wiring includes a metal plug layer and a barrier metal film. A standard electrode potential of a metal that forms the barrier metal film is higher than a standard electrode potential of a metal that forms the variable resistive layer.
