Error correction apparatus, method thereof and memory device comprising the apparatus |
摘要 |
An error correction apparatus, a method thereof, and a memory device including the apparatus are provided. The error correction apparatus may include: a determination unit configured to determine whether a number of errors in a read word being read and extracted from a multi-level cell (MLC) exists in an error correcting capability range; a read voltage control unit configured to either increase or decrease a read voltage applied to the MLC when the number of errors in the read word is outside the error correcting capability range; and a codeword determination unit configured to analyze a bit error based on the increase or decrease of the read voltage, and to select a codeword corresponding to the analyzed bit error based on a selected read error pattern. Through this, it may be possible to efficiently correct a read error that occurs when the data of the memory device is maintained for a long time.
