Abstract:
1. A magnetic memory comprising: a plurality of magnetic junctions, each of the plurality of magnetic junctions including a reference layer, a nonmagnetic spacer layer and a free layer, the free layer being magnetic, the nonmagnetic spacer residing between the free and the reference layer; and at least one semi-spin valve (SSV) line adjacent to the plurality of magnetic junctions, the at least one SSV line including a ferromagnetic layer and a nonmagnetic layer between the ferromagnetic layer and the plurality of magnetic junctions, the SSV line configured to exert a spin accumulation induced torque on at least a portion of the plurality of magnetic junctions due to an accumulation of spin polarized current carriers from a current, the current passing through the at least one SSV line in a current direction, the current direction being substantially perpendicular to a direction between the at least one SSV line and the a magnetic junction of the plurality of magnetic junctions closest to at least a portion of the ferromagnetic layer, the free layer being configured to be written using at least the spin accumulation induced torque.
