Abstract

A nonvolatile memory device comprises overwritable memory cells. In an overwrite operation, data is read from a selected region of the nonvolatile memory device and combined with overwrite data to produce combined data. An error correction code is then generated for the combined data and the overwrite data and the error correction code are stored in the selected region.
