the method of ECC decoder operation and the memory controller including it

摘要

Provided is a method for operating an error correction code (ECC) decoder using a low density parity check (LDPC) code. The ECC decoder receives a first chuck data and a second chuck data which is continuous to the first chuck data from a nonvolatile memory device and performs the error bit correction of the first chunk data. And, the error bit correction of the second chuck data is not performed when the first chuck data includes an error bit which cannot be corrected.
