Patent ID: 7623387

Claim:
A non-volatile storage system, comprising: a set of non-volatile storage elements formed, at least in part, on a substrate, the set of non-volatile storage elements comprises NAND strings which extend between a source side select gate line and a drain side select gate line; a set of word lines associated with the set of non-volatile storage elements, including a selected word line which is associated with at least one non-volatile storage element of the set of non-volatile storage elements, and an isolation word line, a first region of the substrate extends from the isolation word line to the source side select gate line, and a second region of the substrate extends from the isolation word line to the drain side select gate line; and one or more control circuits in communication with the set of non-volatile storage elements, the one or more control circuits boost the first region starting at a first time, and initiate boosting of the second region starting at a second time which is after the first time, and apply a program voltage to the selected word line starting at a third time which is after the second time, and ending at a fourth time which is after the third time, where the first region is boosted between at least the first and third times and the second region is boosted between at least the second and third times, but not between the first and second times.
