Abstract:
A memory device comprises an interconnect comprises a spin orbit coupling (SOC) material. A free magnetic layer is on the interconnect, a barrier material is over the free magnetic layer and a fixed magnetic layer is over the barrier material, wherein the free magnetic layer comprises an antiferromagnet. In another embodiment, memory device comprises a spin orbit coupling (SOC) interconnect and an antiferromagnet (AFM) free magnetic layer is on the interconnect. A ferromagnetic magnetic tunnel junction (MTJ) device is on the AFM free magnetic layer, wherein the ferromagnetic MTJ comprises a free magnet layer, a fixed magnet layer, and a barrier material between the free magnet layer and the fixed magnet layer.
