Patent ID: 8194436

Claim:
A magnetic random access memory comprising: a first ferromagnetic layer; an insulating layer configured to be provided adjacent to said first ferromagnetic layer; and a first magnetization pinned layer configured to be provided adjacent to said insulating layer on a side opposite to said first ferromagnetic layer, wherein said first ferromagnetic layer includes: a magnetization free region configured to have reversible magnetization, and overlap with said first magnetization pinned layer as a second ferromagnetic layer, a first magnetization pinned region configured to have first pinned magnetization and be connected to a part of said magnetization free region, and a second magnetization pinned region configured to have second pinned magnetization and be connected to a part of said magnetization free region, wherein said first ferromagnetic layer has magnetic anisotropy in a direction perpendicular to a film surface, and wherein said first pinned magnetization and said second pinned magnetization are pinned antiparallel to each other in said direction perpendicular to said film surface.
