Patent ID: 7345852

Claim:
A magnetic memory device comprising: a memory cell comprising a first magnetization pinned layer whose magnetization direction is pinned, a first dielectric layer, a magnetic recording layer whose magnetization direction is reversible, a second dielectric layer, and a second magnetization pinned layer whose magnetization direction is pinned, the magnetic recording layer comprising a three-layered film of a first magnetic layer, a nonmagnetic layer and a second magnetic layer, the first and second magnetic layers being anti-ferromagnetically coupled, and a magnetization direction of the first magnetization pinned layer in a region in contact with the first dielectric layer and a magnetization direction of the second magnetization pinned layer in a region in contact with the second dielectric layer being substantially anti-parallel to each other; a bit line extending to a first direction and configured to supply a spin current to the magnetic recording layer through the first or second magnetization pinned layer; and a word line extending to a second direction crossing the first direction and configured to apply a current magnetic field to the magnetic recording layer.
