ABSTRACT:
A memory array having a plurality of resistance variable memory units and method for forming the same are provided. Each memory unit includes a first electrode, a resistance variable material over the first electrode, and a first second-electrode over the resistance variable material. The first second-electrode is associated with the first electrode to define a first memory element. Each memory unit further includes a second second-electrode over the resistance variable material. The second-second electrode is associated with the first electrode to define a second memory element.
