Abstract: A method and system of recovering data includes reading reference codewords, which have code correlation with a target codeword, from a memory device when an error-correcting code (ECC) decoding process for a decoder input of the target codeword has failed. A decoder input of a corrected target codeword is generated based on an operation process using the target codeword and the reference codewords. An ECC decoding process is performed again on the decoder input of the corrected target codeword.
