Abstract
A memory device includes a first terminal and a second terminal; a magnetic tunnel junction coupled to the second terminal; wherein the magnetic tunnel junction comprises a magnetic free layer, and the magnetic tunnel junction is configured to be displaced by a plurality of distances from a center position of the device; a nonmagnetic metallic spin harvesting conductor coupled to the magnetic tunnel junction; wherein the nonmagnetic metallic spin harvesting conductor has a lateral dimension that is larger than that of the magnetic tunnel junction; an electrically insulating spin conductor coupled to the nonmagnetic metallic spin harvesting conductor; wherein the electrically insulating spin conductor has relatively less electrical conductivity than the nonmagnetic metallic spin harvesting conductor; wherein the nonmagnetic metallic spin harvesting conductor collects spin current from the electrically insulating spin conductor; and a spin orbit conduction channel coupled to the electrically insulating spin conductor and to the first terminal.
