Patent ID: 7747817

Claim:
A storage system, comprising: a non-volatile third dimension memory array configured to store data, the data including an address indicating a file location on a disk drive, the third dimension memory array positioned above and in contact with a substrate, the substrate including circuitry fabricated thereon and configured to perform a data operation on the third dimension memory array, the third dimension memory array including a plurality of third dimension memory cells that are arranged in a cross-point array fabricated above the substrate and electrically coupled with the circuitry, each memory cell including a two-terminal memory element configured to store non-volatile data as a plurality of conductivity values and having one terminal electrically coupled with a first conductive array line of the cross-point array and another terminal electrically coupled with a second conductive array line of the cross-point array, the plurality of conductivity values are reversibly switchable by applying a write voltage across the one terminal and the another terminal, and each two-terminal memory element including an electrolytic tunnel barrier having a thickness of less than 50 Å and a mixed valence conductive oxide including mobile oxygen ions, the write voltage operative to reversibly move a portion of the mobile oxygen ions between the mixed valence conductive oxide and the electrolytic tunnel barrier; and a controller configured to process an access request associated with the disk drive, the access request being routed to the circuitry to perform the data operation, wherein data from the data operation is used to create a map of the disk drive.
