Claim Text:
1. A two-terminal re-writeable non-volatile memory element comprising: a first conductive metal oxide (CMO) layer including mobile oxygen ions; a second CMO layer in contact with the first CMO layer and configured to cooperate with the first CMO layer to form an ion obstruction barrier positioned in a portion of both the first CMO layer and the second CMO layer and operative to inhibit transport of other mobile ions when a voltage for data operations is not being applied across a first electrode and a second electrode; and an insulating metal oxide (IMO) layer formed in contact with the second CMO layer; wherein the IMO layer is permeable to the mobile oxygen ions when a write voltage is applied across the first electrode and the second electrode; and wherein the second CMO layer has a second thickness that is less than a first thickness of the first CMO layer.
