    摘要: A nonvolatile memory device comprises a memory controller having a memory cell status estimator that generates status estimation information indicating the status of a memory cell based on status register data, a coupling group index selector configured to generate a select signal for selecting a page and coupling group index from the status estimation information, and a memory cell status value generator configured to map the status estimation information to the data reliability decision bits and the coupling group index and generate a status value of the memory cell for error correction code decoding.
