Abstract:
1. A magnetic memory including one or a plurality of storage areas having magnetoresistance effect elements, wherein each of the magnetoresistance effect elements comprises: a free layer; a pinned layer made of a ferromagnetic material; an intermediate nonmagnetic layer interposed between the free layer and the pinned layer; a writing ferromagnetic material layer which has a direction of magnetization being anti-parallel to that of the pinned layer, and is provided so that the free layer is positioned in a first current path between the writing ferromagnetic material layer and the pinned layer and a first nonmagnetic layer is positioned in the first current path between the writing ferromagnetic material layer and the free layer; and a reading ferromagnetic material layer which has the same direction of magnetization as that of the pinned layer, and is provided so that the free layer is positioned in a second current path between the reading ferromagnetic material layer and the pinned layer and a second nonmagnetic layer is positioned in the second current path between the reading ferromagnetic material layer and the free layer.
