Abstract
In a method of operating the memory system, the method includes detecting whether data of a read-out unit read from a first cell region has an error correction code (ECC) failure, in response to an external read-out request for the read-out unit, recovering and outputting the data of the read-out unit by performing Redundant Array of Inexpensive Disk (RAID) recovery by using data and RAID parity read from other cell regions, recovering a plurality of pieces of data stored in the first cell region by performing the RAID recovery using the data and RAID parity read from the other cell regions, and migrating the recovered plurality of pieces of data to a second cell region in units of cell regions.
