ABSTRACT:
The present invention discloses systems and methods for restoring data in flash memory after an operational failure. The method includes: setting bits of a data buffer in accordance with the data; programming a plurality of memory cells in accordance with the data buffer; and upon failure of the programming step, restoring the data buffer to be set in accordance with the data, wherein the restoring is based only on a present state of the data buffer and on a present state of the plurality of memory cells. A memory device includes: at least one cell; and a controller operative to store data in at least one cell by steps including those described in the method above. The system includes: a memory device that includes at least one cell; and a processor operative to store data in at least one cell by steps including those described in the method above.
