Patent ID: 7505306

Claim:
A magnetic memory device comprising: a semiconductor substrate; a magnetization fixed layer provided above a surface of the semiconductor substrate and having a fixed magnetization direction; a first magnetization free layer provided above the magnetization fixed layer, having variable magnetization direction, and having an easy magnetization axis which extends along a plane intersecting the surface of the semiconductor substrate and along a direction neither parallel nor perpendicular to the surface of the semiconductor substrate; a second magnetization free layer provided above the first magnetization free layer, having a magnetization that antiferromagnetically couples with the first magnetization free layer when no external magnetic field is applied; a first write line provided above and electrically connected to the second magnetization free layer, and extending in a direction that pierces the plane; and a second write line facing at least one of the first magnetization free layer and the second magnetization free layer, and extending along the surface of the semiconductor substrate and the plane and in a direction perpendicular to the first write line.
