1. A device comprising:
a receiver configured to receive a plurality of Error Correction Code (ECC) codewords transmitted from an external device through a channel including one or more lanes;
an ECC decoder configured to generate a plurality of post ECC codewords by performing error correction with respect to the plurality of ECC codewords and generate a first CRC codeword based on the plurality of post ECC codewords;
a CRC checker configured to determine whether an error exists in the first CRC codeword; and
a post ECC decoder configured to, when it is determined that the error exists in the first CRC codeword, generate a second CRC codeword by estimating a remaining error position based on error correction result information received from the ECC decoder and performing remaining error correction with respect to the plurality of post ECC codewords based on the remaining error position.
