Abstract

An operating method is provided which includes receiving a read command and a read address, performing a read operation about memory cells selected according to the read address, and performing a reliability verification read operation about unselected memory cells adjacent to the selected memory cells. A number of memory cells each corresponding to at least one state of an erase state and program states of the unselected memory cells is counted as a count value based on the result of the reliability verification read operation. Data read through the read operation is output to an external device and data read through the reliability verification read operation is not output to the external device.
