Abstract:
1. A magnetic memory, which is configured by disposing therein a plurality of storage areas having magneto-resistance effect elements, wherein each of the magneto-resistance effect elements has an element size of 0.7 μm or smaller, the element being taken in a direction of an easy magnetization axis of the magneto-resistance effect element, and comprises: a free layer composed of a ferromagnetic body; a fixed layer composed of a ferromagnetic body; and an intermediate nonmagnetic layer interposed between the free layer and the fixed layer, each of the storage areas has: switch means for read/write control, which is electrically connected to either one of the fixed layer and the free layer of the each magneto-resistance effect element; a wiring that is electrically connected to the other one of the fixed layer and the free layer of the each magneto-resistance effect element; and a magnetic yoke that surrounds the wiring and applies a magnetic field to the free layer, and the number of the switch means within the each storage area is one.
