ABSTRACT:
A ferromagnetic memory cell is disclosed having a base (21), oriented in a horizontal plane, a bit (19), made of a ferromagnetic material, and a sense/write line (20), positioned proximate the bit (19) sufficient to detect the directed polarity of the bit when a first current is applied thereto, and to direct the polarity of the bit when a second larger current is applied thereto in a given direction. The bit (19) has a height that is oriented perpendicular to the horizontal plane of the base, and a polarity that can be directed along the height.
