Abstract
A method of operating a memory device is disclosed. The memory device includes a memory string coupled with a bit line and a common source line. An erase voltage is applied to the bit line and the common source line in an erase operation. The bit line and the common source line are discharged in a discharge operation after the erase operation. A voltage difference between the bit line and the common source line is less than a first predetermined value during a period of the discharge operation.
