Abstract
A controller for controlling a memory device includes a read control component suitable for controlling a recovery soft read operation of the memory device on bits contained in error correction-failed data groups, when error correction on data of a target data group and error correction on one or more of data of corresponding data groups failed; an error correction code (ECC) component suitable for performing the error correction, and performing a selective data recovery operation on the target data group depending on reliabilities of the respective bits, derived as a result of the recovery soft read operation; and a read bias determiner suitable for determining a recovery soft read voltage to maximize the number of bits recovered by the selective data recovery operation, among bits contained in the target data group.
