Patent ID: 7932573

Claim:
A magnetic memory element having a layer structure comprising: a fixing layer having a magnetization direction fixed unidirectionally, a first nonmagnetic dielectric layer in contact with the fixing layer, a memory layer having a first surface in contact with the first nonmagnetic dielectric layer and a second surface opposing the first surface, the magnetization direction of the memory layer having a reversible magnetization direction in response to the current through the layer structure, a second nonmagnetic dielectric layer in contact with the second surface of the memory laver, and a metal layer in contact with the second nonmagnetic dielectric layer, wherein the memory layer is larger than the fixing layer in plan view, and an end part of the fixing layer is arranged inside an end part of the memory layer in plan view, the memory layer is larger than the metal layer in plan view and an end part of the metal layer is arranged inside an end part of the memory layer in plan view, and the fixing layer is formed approximately corresponding position to the metal layer in plan view while sandwiching the memory layer therebetween.
