Patent ID: 8208297

Claim:
A data storage system including non-Flash re-writeable non-volatile memory, comprising: a plurality of semiconductor die, each die including circuitry fabricated in a logic layer of the die, the circuitry of each die configured to implement a solid state drive (SSD) that emulates at least one hard disk drive (HDD); a plurality of re-writeable non-volatile memories, each re-writeable non-volatile memory is in direct contact with and is fabricated directly above one of the plurality of semiconductor die, each re-writeable non-volatile memory including a plurality of vertically stacked memory layers with each memory layer in direct contact with an adjacent memory layer, each memory layer is positioned in a memory plane that is distinct from memory planes of other memory layers, and each memory layer including at least one non-volatile two-terminal cross-point memory array embedded therein and electrically coupled with the circuitry, at least a portion of the circuitry is configured to perform data operations on the at least one non-volatile two-terminal cross-point memory array, each non-volatile two-terminal cross-point memory array including a plurality of re-writeable non-volatile memory elements, each memory element having exactly two-terminals and configured to store at least one-bit of non-volatile data that is retained in the absence of electrical power; and a memory access circuit included in the circuitry of each die and configured to enable or disable data operations access to a first subset of the plurality of memory elements in its respective re-writeable non-volatile memory in response to a plurality of signals electrically coupled with the memory access circuit, the plurality of signals including access control data and a controllable access address, the access control data is stored in an access control memory included in a second subset of the plurality of memory elements, the memory access circuit including an emulation interface configured to emulate the at least one HDD.
