Patent ID: 7965554

Claim:
A method of adjusting non-volatile storage, comprising: boosting a first set of channel regions to a first voltage range for a first set of non-volatile storage elements without boosting a second set of channel regions to said first voltage range for a second set of non-volatile storage elements, said first set of channel regions and said second set of channel regions are part of a common substrate region by applying a boosting enabling voltage to said first set of non-volatile storage elements, applying a boosting disabling voltage to said second set of non-volatile storage elements, charging said common substrate region and applying signals to unselected word lines for coupling said first set and said second set of non-volatile storage elements to said unselected word lines, and subsequent to said applying voltage signals to said unselected word lines, applying boosting signals beyond said voltage signals to said unselected word lines to boost said first set of channel regions; and applying a common enabling voltage to said first set of non-volatile storage elements and said second set of non-volatile storage elements in order to lower threshold voltages of said first set of non-volatile storage elements without intentionally lowering threshold voltages of said second set of non-volatile storage elements.
