ABSTRACT:
In a particular embodiment, there are a plurality of parallel electrically conductive rows and a plurality of parallel electrically conductive columns crossing the rows, thereby forming a cross-point array with a plurality of intersections. Resistive devices, such as magnetic memory cells, also known as spin valve memory cells, are provided in electrical contact with and located at each intersection. A feedback controlled sense pre-amplifier is also provided to maintain an equi-potential for a given memory cell. A reference voltage is provided to the sense pre-amplifier. As voltage potential, VA′, is provided to the first end of a selected column, contacting a selected memory cell, a feedback voltage VA is provided to the sense pre-amplifier by an independent sense path. The independent sense path connects to the second end of the selected column. The sense pre-amplifier adjusts the applied potential VA to minimize the difference between the feedback and reference voltage.
