Abstract
Decoding method and memory system that decodes data and estimates a weighted checksum on the decoded data to determine whether the decoding is successful. The weighted checksum is calculated based on a first group and a second group, the first group is associated with weights for high degree nodes of an irregular parity check matrix, and the second group is associated with weights for low degree nodes of the irregular parity check matrix.
