Patent ID: 7508042

Claim:
A method to improve performance of a magnetic random access memory, comprising: providing a driver layer having a magnetic easy axis that is normal to said driver layer's surface, whereby said driver layer provides a spin polarized electric current; providing an MTJ magnetic memory element, having an anisotropy field whose direction of magnetization in a free layer may be switched by passing said spin polarized current through said free layer, said spin polarized current having, in the absence of any external magnetic field, a first minimum value; providing a magnetic biasing field generated by a current in a wire that passes over said MTJ; through application of said magnetic biasing field, at a magnitude that about equals or exceeds said anisotropy field, enabling said MTJ free layer to be switched by passing through said free layer a spin polarized current having a second minimum value that is less than said first minimum value; and thereby storing information through use of magnetization switching generated by spin transfer.
