Patent ID: 7978530

Claim:
A non-volatile storage apparatus, comprising: a plurality of non-volatile storage elements on a common substrate region; and one or more managing circuits in communication with the plurality of non-volatile storage elements, the one or more managing circuits program the non-volatile storage elements and identify a subset of the non-volatile storage elements that are over programmed, the one or more managing circuits selectively perform one or more erase operations on the identified subset of non-volatile storage elements that are over programmed by boosting a first set of channel regions to a first voltage range for the identified subset of non-volatile storage elements without boosting a second set of channel regions to the first voltage range for non-volatile storage elements not identified to be over programmed and applying an erase enabling voltage to the identified subset of non-volatile storage elements that are over programmed and non-volatile storage elements not identified to be over programmed, the first set of channel regions and the second set of channel regions are part of the common substrate region.
