摘要： Methods of operating nonvolatile memory devices include reading a first plurality of multi-bit nonvolatile memory cells in the nonvolatile memory device using a first plurality of read voltages to thereby generate first read data, and then rereading the first plurality of multi-bit nonvolatile memory cells using a second plurality of read voltages that differ, at least in part, from the first plurality of read voltages, to thereby generate second read data. An operation is then undertaken to perform first and second ECC decoding operations on the first and second read data, respectively, to thereby identify whether the first read data or the second read data more accurately reflects data stored in the first plurality of multi-bit nonvolatile memory cells during the reading and rereading.
