Patent ID: 8237142

Claim:
A non-Flash re-writeable non-volatile memory device, comprising: a two-terminal cross-point memory array including a plurality of first conductors, a plurality of second conductors arranged substantially orthogonally to the plurality of first conductors, an un-etched first electrically insulating layer having a first thickness less than approximately 50 Angstroms, and a un-etched conductive metal oxide (CMO) layer including a plurality of electrically conductive crystallized portions having mobile oxygen ions, the CMO layer is in direct contact with the first electrically insulating layer, the first electrically insulating layer and the CMO layer are positioned between the plurality of first and second conductors, direct contact between the first electrically insulating layer and the plurality of the electrically conductive crystallized portions operative to form a plurality of re-writeable non-volatile two-terminal memory elements, each memory element is positioned between a cross-point of one of the plurality of first conductors with one of the plurality of second conductors and includes a first portion of the first electrically insulating layer that is in direct contact with the crystallized portion and the first portion is permeable to the mobile oxygen ions during write operations to the memory element, each memory element including a first terminal directly electrically coupled with its respective first conductor and in direct contact with its respective crystallized portion and a second terminal directly electrically coupled with its respective second conductor and in direct contact with the first portion, wherein each memory element is directly electrically in series with its first and second terminals and with its respective first and second conductors.
