Patent ID: 8040724

Claim:
A magnetic random access memory comprising: a magnetic recording layer configured to include a ferromagnetic layer and have perpendicular magnetic anisotropy; and a magnetic reading layer configured to be provided on said magnetic recording layer and be used for reading information; wherein said magnetic recording layer includes: a magnetization switching area configured to have reversible magnetization, a first magnetization pinned area configured to be connected to a first boundary of said magnetization switching area and have magnetization whose direction is pinned in a first direction, and a second magnetization pinned area configured to be connected to a second boundary of said magnetization switching area and have magnetization whose direction is pinned in a second direction, wherein said magnetic reading layer includes: a magnetic sensing layer whose direction of magnetization changes based on a direction of said magnetization of said magnetization switching area, a nonmagnetic barrier layer configured to be provided on said magnetic sensing layer, and a pinned layer configured to be provided on said nonmagnetic barrier layer.
