Patent ID: 7870333

Claim:
An integrated circuit for a disk controller including embedded non-volatile third-dimensional memory, comprising: at least one non-volatile third dimension two-terminal memory array, at least a portion of the at least one non-volatile third dimension two-terminal memory array operative to store non-volatile access data for access request on at least one disk drive, the at least one non-volatile third dimension two-terminal memory array including a plurality of two-terminal memory elements arranged in a cross-point array configuration and operative to store non-volatile data as a plurality of conductivity profiles, each two-terminal memory element including an electrolytic tunnel barrier having a thickness less than 50 Å in contact with a mixed valence conductive oxide including mobile oxygen ions that are moveable between the electrolytic tunnel barrier and the mixed valence conductive oxide in response to a write voltage applied across the two-terminal memory element; a substrate including access circuitry and disk controller circuitry formed on the substrate, the access circuitry configured to perform data operations on the at least one non-volatile third dimension two-terminal memory array, the disk controller circuitry is electrically coupled with the access circuitry, the least one disk drive, and the external system, the disk controller circuitry configured to access and operate on the non-volatile access data to perform the access requests on the least one disk drive in response to commands from the external system, and the at least one non-volatile third dimension two-terminal memory array is in contact with and is fabricated directly above the substrate and is electrically coupled with the access circuitry.
