摘要：An operation method of a flash memory system includes: performing harddecision 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 concatenatedBCH (BC-BCH) method; identifying a location of an error message block to which the harddecision decoding fails among a plurality of the message blocks, when the hard decisiondecoding fails; generating soft decision information corresponding to the row constituentcodes and the column constituent codes of the error message block; and performingsoft decision decoding on the error message block based on the soft decisioninformation.
