A magnetic memory device includes a magnetization fixed layer provided above a semiconductor substrate surface and having a fixed magnetization direction. A first magnetization free layer is provided above the magnetization fixed layer, has variable magnetization direction, and has an easy magnetization axis extending along a plane intersecting the substrate surface and along a direction neither parallel nor perpendicular to the substrate surface. A second magnetization free layer is provided above the first magnetization free layer, has a magnetization that antiferromagnetically couples with the first magnetization free layer. A first write line is placed above and electrically connected to the second magnetization free layer, and extends in a direction that pierces the plane. A second write line faces the first and/or second magnetization free layer, and extends along the substrate surface and the plane and in a direction perpendicular to the first write line.
