Abstract
A method of operating a memory device includes applying a first erase voltage to a source line in an erase operation of a memory block connected between the source line and bit lines. The method also includes decreasing a voltage of the source line to which the first erase voltage is applied to a second erase voltage and then increasing a voltage of the source line to which the second erase voltage is applied to a third erase voltage. The magnitude of the second erase voltage is between the magnitudes of the first and third erase voltages.
