Patent ID: 8565010

Claim:
A spin toque transfer magnetic random access memory (STTMRAM) element configured to store a state when electrical current is applied thereto comprising: a pinned layer having a perpendicular magnetic component associated therewith that is fixed in a first direction; a coupling layer formed on top of the pinned layer; a reference layer formed on top of the coupling layer and having a perpendicular magnetic component associated therewith that is fixed in a second direction substantially opposing the first direction; a junction layer formed on top of the reference layer; a free layer formed on top of the junction layer and having a magnetic orientation perpendicular relative to the plane of the substrate, the free layer being capable of changing states by switching its magnetic orientation when electrical current is applied to the STTMRAM element; a spacer layer formed on top of the free layer, the spacer layer comprising at least one insulating layer; a fixed layer formed on top of the space layer, the fixed layer having a perpendicular magnetic component associated therewith that is fixed in the first direction, the free layer having associated therewith an in-plane magnetic field at the edge thereof, along a radial direction, generated by the fixed layer, the pinned layer, and the reference layer, the in-plane magnetic field having a magnitude that is equal to or greater than 1 kilo Oersted (kOe), the free layer further having associated therewith a coercive field that is smaller in the presence of the in-plane magnetic field, wherein a perpendicular magnetic field within the free layer, generated by the fixed layer, the pinned layer and the reference layer, substantially cancel each other.
