Abstract
Systems and methods presented herein provide for open block handling of an SSD. In one embodiment, an SSD includes a buffer, and an MLC flash device. The SSD also includes a controller operable to write data in the buffer based on an Input/Output (I/O) request (e.g., from a host), to begin copying the data from the buffer to a block of the MLC flash device, to copy a portion of the data associated with open word lines of the block to another location in the buffer after a power cycle, and to update a lookup table for the copied portion of the data with the other location so that the copied portion of the data can be accessed via a subsequent I/O request.
