Abstract
A memory system includes a non-volatile memory device and a controller. The non-volatile memory device includes plural memory groups storing plural chunks. The controller is capable of generating 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 recovering at least one chunk among the plural chunks based on the different priorities when an operation regarding the at least one chunk fails.
