IMPLEMENTATION OF RECYCLING UNUSED ECC PARITY BITS DURING FLASH MEMORY PROGRAMMING

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...

Summary: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.
