Abstract
A solid-state drive includes a flash memory device, a power loss protection circuit, a dynamic random access memory (RAM) coupled to the power loss protection circuit, and a controller configured to direct I/O requests to either the flash memory drive or the RAM. Because the controller can direct I/O request to the RAM, the RAM is revealed as a separate mass storage device to a host. Consequently, the RAM provides additional and significantly higher performance storage capacity to the solid-state drive.
