Abstract
A method for operating a data storage device using, as a storage medium, a nonvolatile memory device including a memory cell array which is constructed by pages including data cells and flag cells for storing whether upper bit (MSB) data is stored in a data cell, includes searching a last programmed page in the case where recovery is made from a power failure to a normal state; determining whether the last programmed page is an upper bit (MSB) page to be accessed to store upper bit (MSB) data; and adjusting a flag cell read voltage for reading flag cells, in the case where the last programmed page is an upper bit (MSB) page.
