Patent ID: 8598576

Claim:
A spin transfer torque magnetic random access memory (STTMRAM) element configured to store a state when electrical current is applied thereto comprising: a reference layer formed on a substrate with a plane, the reference layer and having a perpendicular magnetization associated therewith that is fixed in one direction; a junction layer formed on top of the reference layer; a free layer having a center and formed on top of the junction layer and having a magnetization at substantially the center of the free layer that is perpendicular relative to the plane of the substrate, the free layer being capable of changing states by switching its magnetization when electrical current is applied to the STTMRAM element; a spacer layer formed on top of the free layer; and a fixed layer formed on top of the spacer layer, the fixed layer having a perpendicular magnetization associated therewith that is fixed in a direction opposite to that of the reference layer, the magnetization of the free layer being parallel and switching relative to that of the reference layer, wherein an in-plane magnetic field is generated at an edge of the free layer by the fixed layer and the reference layer, the free layer further having associated therewith a coercively field that is smaller in the presence of the in-plane magnetic field.
