Patent ID: 8031509

Claim:
A pyrochlore non-volatile memory cell, comprising: a first terminal structure; a second terminal structure; and a memory element electrically in series with the first and second terminal structures and operative to store data as a plurality of conductivity profiles, the memory element including an electrolytic insulator in contact with the first terminal structure and including a first thickness configured to allow tunneling conduction, and a conductive metal oxide (CMO) including mobile oxygen ions and made from a pyrochlore oxide material having a crystalline structure, the CMO is in contact with the electrolytic insulator and with the second terminal structure, wherein the pyrochlore oxide material includes a form A 2 B 2 O 7 , where O represents oxygen, A represents at least one rare-earth element, and B represents a selected one of a rare-earth element or a transition metal element.
