Abstract
Methods for recycling unused error correction code (ECC) during flash memory programming, comprise generating ECC from user data to form a syndrome and storing the syndrome into volatile memory. ECC is re-encoded corresponding to the syndrome read from the memory with new user data. Re-encoding ECC comprises comparing new ECC with the most recent ECC of the previous syndrome, correcting a bit error in the new ECC, and indicating if the new ECC has failed.
