  • Patent number: 10942805
    Abstract: An error correcting circuit receives a codeword including user data and a parity code, and performs an error correction operation on the user data. The circuit includes a first buffer, a decoder, a second buffer and a processor. The first buffer stores the codeword and sequentially outputs pieces of subgroup data obtained by dividing the codeword. The decoder generates pieces of integrity data for each of the pieces of subgroup data received from the first buffer, and performs the error correction operation on the user data using the parity code. The second buffer sequentially stores the pieces of integrity data for each of the pieces of subgroup data. The processor determines whether an error is present in the codeword based on the pieces of integrity data stored in the second buffer when at least one of the pieces of integrity data is updated in the second buffer.

  • Patent number: 10846174
    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.
