Abstract
A method of enhancing an error correction performance in a data storage system, and a storage device using the method, determines a deterioration status of a physical area of a memory device to which data is to be stored and compresses data and stores the compressed data and an error correction code (ECC) with respect to the compressed data in an area of which the deterioration status is equal to or greater than a threshold value that is initially set and stores uncompressed data and an ECC with respect to the uncompressed data in an area of which the deterioration status is less than the threshold value.
Claims15
A method of enhancing an error correction performance, the method comprising:
- determining a deterioration status of a physical area of a memory device to which data is to be stored;
- and
- compressing data and storing the compressed data and an error correction code (ECC) with respect to the compressed data in an area of which the deterioration status is equal to or greater than a threshold value that is initially set;
- and
- storing uncompressed data and an ECC with respect to the uncompressed data in an area of which the deterioration status is less than the threshold value.
A method of enhancing an error correction performance, the method comprising:
- determining a deterioration status of a physical area of a memory device;
- and
- compressing data and storing the compressed data and an error correction code (ECC) to the physical area if the deterioration status of the physical area is equal to or greater than a threshold value;
- and
- storing uncompressed data and an ECC to the physical area if the deterioration status of the physical area is less than the threshold value.
