Classification: CPC G | IPC G

Claim 0:
1. A non-volatile memory device, comprising:
a plurality of word lines; and
a control circuit configured to:
apply a first word line pre-pulse signal of a plurality of word line pre-pulse signals to a first group of the plurality of word lines,
apply a second word line pre-pulse signal of the plurality of word line pre-pulse signals to a second group of the plurality of word lines during a pre-charge period, and
apply a third word line pre-pulse signal of the plurality of word lines pre-pulse signals to a third group of the plurality of word lines during the pre-charge period,
wherein a voltage level of the second word line pre-pulse signal is greater than that of the first word line pre-pulse signal, and a voltage level of the third word line pre-pulse signal is greater than that of the second word line pre-pulse signal.
