    摘要: An operating method of a memory system includes: reading a first data from a particular data group among a plurality of data groups included in a memory device; performing a first error correction code (ECC) decoding for the first data; when the first ECC decoding fails, reading a plurality of the remaining data other than the first data from the particular data group; performing a second ECC decoding for the plurality of the remaining data; when the second ECC decoding fails, identifying data, to which the second ECC decoding fails, among the plurality of the remaining data; obtaining first and second soft read values respectively corresponding to the first data, to which the first ECC decoding fails, and the second data, to which the second ECC decoding fails; determining reliability of the first and second data based on the first and second soft read values; and correcting the first data based on the reliability of the first and second data.
