SUPPORTING MULTIPLE PAGE LENGTHS WITH UNIQUE ERROR CORRECTION CODING VIA GALOIS FIELD DIMENSION FOLDING

摘要

Disclosed are methods and devices for supporting multiple page lengths with unique error correction coding via Galois field dimension folding. In one embodiment, a method comprises receiving a write instruction, the write instruction including user data; generating extended user data based on the user data, the extended user data including at least one symbol comprising a bit of the user data and a pre-stored bit pattern; generating parity data by encoding the extended user data; generating parity extension data by encoding the bit of the user data; writing a codeword to a page of a non-volatile memory device, the codeword including the parity extension data, the user data, and the parity data.
