Claim 0:
1. A magnetic memory device, comprising:
a first magnetic memory device;
a second magnetic memory device connected to the first magnetic memory device;
a pulse power supplying current pulses to the first and second magnetic memory devices; and
a switch configured to selectively connect the pulse power to one of the first and second magnetic memory devices,
wherein each of the first and second magnetic memory devices comprises a first fixed layer, a first non-magnetic layer, a free layer, a second non-magnetic layer, and a second fixed layer, which are sequentially stacked, the first fixed layer having a magnetization direction maintained in a fixed direction, the free layer having a perpendicular magnetic anisotropy and a variable magnetization direction, the second fixed layer having a magnetization direction maintained in an opposite direction of the first fixed layer, and
a resistance value of an MTJ device composed of the first fixed layer, the first non-magnetic layer, and the free layer is different from a resistance value of an MTJ device composed of the second fixed layer, the second non-magnetic layer, and the free layer.
