Abstract
A method includes performing a read operation that reads data from a group of analog memory cells using at least one read threshold, to produce readout results. A detection is made that the read threshold is set in a restricted range that causes the readout results not to reflect the read threshold. The data is reproduced from the group of the memory cells while compensating for the read threshold that is set in the restricted range.
