NONVOLATILE MEMORY DEVICE, OPERATING METHOD THEREOF, AND DATA STORAGE DEVICE INCLUDING THE SAME

摘要

A nonvolatile memory device includes a memory cell array including a data cell area, and a mode cell area that stores write mode information of the data cell area, a mode information storage block storing previous write mode information read out from the mode cell area in a previous read operation, and a control logic reading out the write mode information from the mode cell area comparing the read-out write mode information and the previous write mode information, and reading the data cell area in a read mode selected based on a comparison result.
