Abstract:
1. A soft-reference four conductor magnetic memory storage device comprising: a plurality of parallel electrically conductive first sense conductors; a plurality of parallel electrically conductive second sense conductors crossing the first sense conductors, thereby forming a sense cross point array with a plurality of intersections; a plurality of soft-reference magnetic tunnel junction memory cells, each cell in electrical contact with and located at an intersection between a first sense conductor and a second sense conductor, the memory cells comprising a material with an alterable orientation of magnetization; a plurality of parallel electrically conductive write rows substantially proximate to and electrically isolated from the first sense conductors; and a plurality of parallel electrically conductive write columns crossing the write rows, substantially proximate to and electrically isolated from the second sense conductors, thereby forming a write cross point array with a plurality of intersections.
