Abstract:
1. A non-volatile storage system, comprising: a set of non-volatile storage elements; and one or more managing circuits in communication with the set of non-volatile storage elements, the one or more managing circuits receive a request to program data, and, responsive to the request: (a) program a selected non-volatile storage element in the set by applying a programming voltage on a selected word line, (b) during the programming, apply a first voltage to at least a first word line which is associated with a previously programmed non-volatile storage element in the set to boost a potential of a first associated channel region, and applying a second voltage to at least a second word line which is associated with an unprogrammed and/or partly programmed non-volatile storage element in the set to boost a potential of a second associated channel region, the first voltage being greater than the second voltage, and (c) during the programming, form an isolation region between the first and second associated channel regions by applying third through fifth voltages to third through fifth word lines, respectively, that are between the selected word line and the at least a first word line, the fourth word line being between the third and fifth word lines, the third through fifth voltages being less than the first voltage, and the fourth voltage being less than the third and fifth voltages.
