Zusammenfassung: | A nonvolatile memory device includes a control unit configured to measure a threshold voltage distribution of each of selected pages between a start voltage and an end voltage by performing a read operation on each page in response to a command set for analyzing the threshold voltage distribution, to compare the measured threshold voltage distribution with a reference threshold voltage distribution, and to determine a read voltage having a least amount of errors upon the read operation being performed. |
