Abstract

A symmetric magnetic tunnel device including first and second magnetic tunnel junctions each including a pinned magnetic layer, an insulating tunnel layer and a free magnetic layer stacked in parallel juxtaposition to allow tunneling of electrons through the insulating tunnel layer between the pinned and free magnetic layers. The first and second magnetic tunnel junctions positioned in parallel juxtaposition so as to form a continuous electron path through the first and second magnetic tunnel junctions and to provide a cell signal across the first and second magnetic tunnel junctions greater than a cell signal across each of the first and second magnetic tunnel junctions individually.
