Abstract
A memory system includes a non-volatile memory device including plural memory groups storing plural chunks; and a controller configured to generate the plural chunks including data chunks and parity chunks based on original data, assign different priorities to the data chunks and the parity chunks, and recover at least one chunk among the plurality of chunks based on the different priorities when an operation regarding the at least one chunk fails.
