US Patent 7747817 Performing data operations using non-volatile third dimension memory

Performing data operations using non-volatile third dimension memory is described, including a storage system having a non-volatile third dimension memory array configured to store data, the data including an address indicating a file location on a disk drive, and a controller configured to process an access request associated with the disk drive, the access request being routed to the non-volatile third dimension memory array to perform a data operation, wherein data from the data operation is used to create a map of the disk drive. In some examples, an address in the non-volatile third dimension memory array provides an alias for another address in a disk drive.
