The non-volatile memory device includes a plurality of memory regions, each memory region including a plurality of cells commonly coupled to a word line. The controller generates a plurality of candidate data sets based on source data, determines a number of vulnerable cells corresponding to each of the plurality of candidate data sets, and stores a candidate data set having a smallest number of vulnerable cells into a target memory region among the plurality of memory regions.
