Abstract:
A method for correcting a cell voltage driftage in a NAND flash device is disclosed. An indicator indicating a cell voltage driftage in a memory unit of a NAND flash device is monitored by a processor. A cell voltage driftage in the NAND flash device is detected based at least in part on the indicator. One or more NAND commands correcting the cell voltage driftage are generated. The one or more NAND commands include a NAND command associated with changing a configuration setting of the NAND flash device.
