    摘要: An operation method of a flash memory system includes: performing hard decision decoding on a codeword, which is encoded in units of message blocks with row constituent codes and column constituent codes according to a block-wise concatenated BCH (BC-BCH) method; identifying a location of an error message block to which the hard decision decoding fails among a plurality of the message blocks, when the hard decision decoding fails; generating soft decision information corresponding to the row constituent codes and the column constituent codes of the error message block; and performing soft decision decoding on the error message block based on the soft decision information.

    摘要: The present disclosure relates to a BCH encoding, decoding, and multi-stage decoding circuits and method, and an error correction circuit of a flash memory device using the same. The concatenated BCH multi-stage decoding circuit includes: a first stage encoding unit that receives a part or all of data input to a flash memory device, performs BCH encoding, and outputs a first output BCH code or a parity bit thereof; an interleaving unit that receives a part or all of data input to the flash memory device, interleaves, and outputs the data, and a second stage encoding unit that performs BCH encoding of the BCH code or data that is the output of the interleaving unit, and outputs a second output BCH code or a parity bit thereof.

    摘要: A concatenated error correction device may be provided that includes: a first encoder which encodes a plurality of blocks arranged in a column direction and a row direction into a block-wise product code consisting of column codes and row codes by applying a first error correction code to the blocks in each of the column direction and the row direction; and a second encoder which receives K number of source symbols and applies a second error correction code to the source symbols, and then encodes into N number of symbols including N-K number of parity symbols. The N number of symbols form the plurality of blocks. K and N are natural numbers.
