Patent ID: 6970376

Claim:
A magnetic random access memory comprising: a first write wiring extended in a first direction; a second write wiring extended in a second direction different from the first direction; a magneto-resistance element provided at a point of intersection of the first and second write wirings and located between the first and second write wirings; a first yoke layer provided on a first outer surface and both sides of the first write wiring and being formed of a magnetic layer, the first outer surface being opposite a first inner surface of the first write wiring facing the magneto-resistance element; and a second yoke layer provided on a second outer surface and both sides of the second write wiring and being formed of a magnetic layer, the second outer surface being opposite a second inner surface of the second write wiring facing the magneto-resistance element, wherein the magneto-resistance element has: a recording layer formed of a ferromagnetic substance and comprising a first surface and a second surface; a first ferromagnetic layer provided on the first surface of the recording layer; a second ferromagnetic layer provided on the second surface of the recording layer; a first nonmagnetic layer provided between the recording layer and the first ferromagnetic layer; and a second nonmagnetic layer provided between the recording layer and the second ferromagnetic layer.
