US Patent 7979614 Flash memory/disk drive interface and method for same

A disk controller for coupling a disk drive to a host includes an interface controller and a buffer memory. The interface controller is configured to interface the disk drive to the host using a NAND flash memory interface having a 14-line bus. The interface controller includes a flash controller configured to emulate data transfer protocols of the disk drive, including interpreting flash commands received from the host via the 14-line bus of the NAND flash memory interface, and generating control signals to control the disk drive. The control signals are generated based on the interpreted flash commands. The buffer memory is configured to store data received from the host and the disk drive.
