Abstract:
Spin-orbit-torque (SOT) control strip lines are provided along the sides of free layers in perpendicular magnetic tunnel junction devices. Current flowing through such SOT control strip lines injects spin current into the free layers such that spin torque is applied to the free layers. The spin torque can be used to force the magnetic state of the free layer to a particular state based on the direction of the current through the SOT control strip line. In other embodiments, the SOT provides an assist to spin-transfer torque generated by current flowing vertically through the magnetic tunnel junction. Some embodiments have dedicated strip lines for a single magnetic tunnel junction such that a three-terminal device results. Other embodiments have multiple magnetic tunnel junctions sharing a strip line, where the strip line can be used to reset all of the magnetic tunnel junctions to the same state and can also be used as an assist such that individual magnetic tunnel junctions can be written using selection circuitry.

Claim (Index 14):
An apparatus, comprising:\n a magnetic tunnel junction that includes:\n a free layer, wherein the free layer has a magnetic state, wherein an easy axis for the magnetic state of the free layer is perpendicular to a film plane in which the free layer is formed; \n a dielectric layer under the free layer; and \n a reference layer under the dielectric layer, the reference layer having stable magnetic states with magnetization direction perpendicular to the film plane; and \n a spin-orbit-torque control strip line on a side surface of the free layer, wherein the side surface is perpendicular to the film plane and current in the spin-orbit-torque control strip line causes spin current in the free layer, wherein the spin current is perpendicular to the side surface of the free magnetic layer and parallel to the film plane.
