This invention provides a soft-reference four conductor magnetic memory storage
device. In a particular embodiment, there are a plurality of parallel electrically
conductive first sense conductors and a plurality of parallel electrically conductive
second sense conductors. The first and second sense conductors may provide a cross
point array or a series connected array. Soft-reference magnetic memory cells are
provided in electrical contact with and located and at each intersection. In addition
there are a plurality of parallel electrically conductive write rows substantially
proximate to and electrically isolated from the first sense conductors. A plurality
of parallel electrically conductive write columns transverse to the write rows,
substantially proximate to and electrically isolated from the second sense conductors,
forming a write cross point array with a plurality of intersections, is also provided.
Sense magnetic fields generated by at least one conductor orient the soft-reference
layer but do not alter the data stored within the cell. An associated method of
use is also provided.
