Abstract:
According to one embodiment, in a nonvolatile semiconductor memory device, a first line is disposed on a semiconductor substrate. A first memory cell is disposed on a side opposite to the semiconductor substrate with respect to the first line. A second line intersects with the first line via the first memory cell. A second memory cell is disposed on a side opposite to the semiconductor substrate with respect to the second line. A third line intersects with the second line via the second memory cell. The first memory cell has a first resistance change layer and a first rectification layer. The second memory cell has a second resistance change layer and a second rectification layer. A composition of the first resistance change layer is different from a composition of the second resistance change layer.
