Abstract
A data storage device includes at least one nonvolatile memory device; and a controller suitable for: generating parity data for data; performing a write operation for storing the data in at least one first memory region corresponding to at least one word line of the nonvolatile memory device; and selectively storing the parity data in at least one second memory region corresponding to the word line according to a size of the data, wherein the controller generates a plurality of parity data for the data according to respective types of the first memory region where the data are to be stored, and performs the write operation by storing parity data corresponding to respective types of the second memory region among the plurality of parity data, in the second memory region.
