Abstract
According to a certain embodiment, the 3D stacked semiconductor memory includes: a first electrode line extending in a first direction orthogonal to the semiconductor substrate; a second electrode line adjacent to the first electrode line in a second direction orthogonal to the first direction, and extending in the first direction; a first variable resistance film extending in the first direction and in contact with the second electrode line; a first semiconductor film in contact with the first variable resistance film and the first electrode line; a first potential applying electrode extending in the second direction and in contact with a first insulator layer; a second semiconductor film in contact with a second variable resistance film and the first electrode line; and a second potential applying electrode extending in the second direction and in contact with a second insulator layer. The first and second potential applying electrodes are electrically different nodes.
