Patent ID: 7701834

Claim:
An apparatus comprising: a plurality of first electrodes; at least one second electrode; and a storage medium fixed to the at least one second electrode and electrically coupled to both the plurality of first electrodes and the at least one second electrode, the storage medium having a plurality of memory elements, each memory element having a conductance that is responsive to a write voltage across one of the first electrodes and the at least one second electrode without the storage medium undergoing a phase change and without the plurality of first electrodes applying heat or force to deform a surface of the storage medium; wherein the plurality of first electrodes are movable relative to the at least one second electrode, wherein the storage medium includes a conductive metal oxide and a tunnel barrier in contact with the conductive metal oxide, forming an interface between the conductive metal oxide and the tunnel barrier, and wherein the write voltage causes oxygen ions to move across the interface.
