US Patent 7492631 Methods involving resetting spin-torque magnetic random access memory

An exemplary method for resetting a spin-transfer based random access memory system, the method comprising, inducing a first current through a conductor, wherein the first current is operative to change a direction of orientation of a magnetic reference layer, inducing a second current from the drain terminal to the write terminal via a conductive layer, wherein the second current is operative to change the direction of a magnetic state of a free layer magnet, and inducing a third current through the conductor, wherein the third current is operative to change the direction of magnetic orientation of the reference layer.
