Abstract:
A data storage device includes a nonvolatile memory device including a plurality of memory cells; and a controller suitable for determining whether the memory cells are erased or not, wherein, when it is determined, based on first data read as a read voltage set including a first read voltage is applied to the memory cells, that the memory cells are not erased, the controller determines whether the memory cells are erased or not based on second data read as the read voltage set in which the first read voltage is replaced with a second read voltage is applied to the memory cells, and wherein the first and second read voltages are read voltages of lowest levels among read voltages included in the read voltage set.

Claim (Index 15):
A method for operating a data storage device, comprising:\n determining whether memory cells are erased or not based on first data obtained by applying a read voltage set including a first read voltage to the memory cells; performing an error correction operation for the first data, when it is determined as a result of the determining that the memory cells are not erased; obtaining second data by applying the read voltage set in which the first read voltage is replaced with a second read voltage, when the error correction operation fails; and determining whether the memory cells are erased or not based on the second data, wherein the first and second read voltages are read voltages of lowest levels among read voltages included in the read voltage set.
