An operating method of a memory controller is provided. The method includes: in a first super block including first blocks of memory chips, storing a first read level with respect to a first block in a first memory as first super block read level (RL) information; storing the first read level in a second memory as first chip RL information corresponding to the first memory chip; during the read operation on the first blocks included in the first super block, controlling the read operation based on the first super block RL information stored in the first memory; and based on a failure occurring in data read from the first block of the first memory chip by using the first super block RL information, controlling the read operation on the first block of the first memory chip based on the first chip RL information stored in the second memory.
