In a Low-Density Parity-Check (LDPC) ECC decoder, a syndrome weight for a codeword is a number of unresolved equations, or unsatisfied check nodes, when the codeword is decoded. On average, the greater the number of unsatisfied check nodes (higher syndrome weight) the higher the number of errors in the codeword. On average, the fewer the number of unsatisfied check nodes (higher syndrome weight) the lower the number of errors in the codeword. Thus, in certain instances, a codeword with fewer errors may still have a greater the number of unsatisfied check nodes (higher syndrome weight).
