Zusammenfassung:According to one embodiment, a semiconductor memory device includes a plurality of first wirings, a plurality of second wirings, a variable resistance layer, a first barrier insulating layer, and a second barrier insulating layer. The first wirings are disposed at predetermined pitches in a first direction intersecting with a substrate. The second wirings are disposed at predetermined pitches in a second direction intersecting with the first direction. The second wirings are formed to extend in the first direction. The variable resistance layer is disposed between the first wiring and the second wiring. The variable resistance layer is disposed at a position where the first wiring intersects with the second wiring. The first barrier insulating layer is disposed between the first wiring and the variable resistance layer. The second barrier insulating layer is disposed between the second wiring and the variable resistance layer.
