Abstract
A nonvolatile storage device adapted for use with computers, workstations and other processing apparatuses. The storage device includes a printed circuit board, a nonvolatile memory array comprising at least two sub-arrays that contain nonvolatile solid-state memory devices, and control circuitry for interfacing with the processing apparatus. The control circuitry includes an abstraction layer and at least two memory control units configured to communicate data, address and control signals with the sub-arrays of the memory devices. A bus connects each memory control unit to a corresponding one of the sub-arrays. The control circuitry further includes a crossbar switch that functionally connects each memory control unit to the abstraction layer. The storage device is capable of overcoming limitations of current SSD designs by enabling independent read and write transfers (accesses) to the memory devices of the storage device, including concurrent read and write accesses.
