Abstract
A method for operating a data storage device includes reading out a data chunk from a nonvolatile memory device; arranging first codes and second codes of the read-out data chunk in the form of a matrix; and determining the total number of corrected error bits for the data chunk by decoding the respective first codes and the respective second codes, and summing the numbers of corrected error bits of the respective decoded first codes and the respective decoded second codes.

A method for operating a data storage device, the method comprising:
- reading out a data chunk from a nonvolatile memory device;
- arranging first codes and second codes of the read-out data chunk in the form of a matrix;
- and
- determining the total number of corrected error bits for the data chunk by decoding the respective first codes and the respective second codes, and summing the numbers of corrected error bits of the respective decoded first codes and the respective decoded second codes.

A data storage device comprising:
- a nonvolatile memory device in which a data chunk is stored;
- a control unit suitable for reading out the data chunk from the nonvolatile memory device;
- and
- an error correction code (ECC) unit suitable for:
- arranging first codes and second codes of the read-out data chunk in the form of a matrix, and
- determining the total number of corrected error bits for the data chunk by performing a decoding operation for the respective first codes and the respective second codes, and counting and summing the numbers of corrected error bits of the respective decoded first codes and the respective decoded second codes.
