Abstract:
Disclosed herein is a semiconductor memory device, including: a first electrode formed on a substrate; an ion source layer formed on an upper layer of the first electrode; and a second electrode formed on an upper layer of the ion source layer. Resistance change type memory cells in each of which either a surface of the first electrode or a surface of the ion source layer is oxidized to form a resistance change type memory layer in an interface between the first electrode and the ion source interface are arranged in a array.
