Abstract
In a non-volatile memory device, the level of a verifying voltage supplied to a word line is adjusted in accordance with occurrence of a source line bouncing phenomenon. The non-volatile memory device includes a bouncing sensing circuit configured to compare a source line current passing through a common source line with a reference current, and output a bouncing sensing signal in accordance with the comparing result, and a word line voltage controller configured to provide a verifying voltage increased by a certain level to a word line in accordance with level of the bouncing sensing signal.
