Patent ID: 8514615

Claim:
A spin-torque magnetoresistive memory comprising: a plurality of magnetoresistive memory elements formed from a plurality of layers defining a film plane; a first conductive reset line positioned adjacent each of the plurality of magnetoresistive memory elements and configured to set the plurality of magnetoresistive memory elements to a known magnetic state having magnetization perpendicular to the film plane by generating a magnetic field with a predominant component perpendicular to the film plane when an electrical current of predetermined magnitude, duration, and direction flows through the first conductive reset line; a first permeable ferromagnetic material positioned on at least one side of the first conductive reset line and having at least one edge positioned parallel to the film plane and outside of the film plane; a bit line coupled to the plurality of magnetoresistive memory elements; and circuitry coupled to the bit line and configured to apply a spin torque transfer current through the bit line to selected ones of the plurality of magnetoresistive memory elements.
