Abstract:
Methods and devices for sensing non-volatile storage are disclosed. Technology disclosed herein reduces the time for sensing operations of non-volatile storage such as read and program verify. In one embodiment, a kicking voltage is applied to a selected word line during a sensing operation. The kicking voltage may be applied to one end of a selected word line during a transition from a first reference voltage to a second reference voltage. The kicking voltage may help the other end of the word line reach the second reference voltage quickly. Since the bit lines can be sensed after the selected word line has reached the target reference voltage, the time delay prior to sensing of the bit lines may be reduced.
