Abstract
Spin-orbit-torque (SOT) lines are provided near free regions in magnetoresistive devices that include magnetic tunnel junctions. Current flowing through such SOT lines injects spin current into the free regions such that spin torque is applied to the free regions. The spin torque generated from a SOT switching line can be used to switching the free region or to act as an assist to spin-transfer torque generated by current flowing vertically through the magnetic tunnel junction, in order to improve the reliability, endurance, or both of the magnetoresistive device. Further, one or more additional layers or regions may improve the SOT switching efficiency and the thermal stability of magnetoresistive devices including SOT lines.
