Abstract:
1. An orthogonal spin-torque bit cell, comprising: a perpendicular magnetized polarizing layer having a magnetic vector, wherein the perpendicular magnetized polarizing layer provides a first spin-torque; an in-plane magnetized free layer; an element used to change the magnetic vector of the perpendicular magnetized polarizing layer to be magnetized up or down along an axis perpendicular to a plane of the perpendicular magnetized polarizing layer; and a reference layer that provides a second spin-torque, wherein the first spin-torque and the second spin-torque combine, wherein the magnetic vector of the perpendicular magnetized polarizing layer affects combination of the first spin-torque and the second spin-torque, wherein the in-plane magnetized free layer and the reference layer form a magnetic tunnel junction, and wherein the combined first spin-torque and second spin-torque influences the magnetic state of the in-plane magnetized free layer.
