Abstract:
1. A method for operating non-volatile storage, comprising: (a) performing program and verify operations on a particular storage element in a set of series-connected storage elements to raise a threshold voltage of the particular storage element to a first verify level, and during the verify operations, applying a first pass voltage to an adjacent storage element of the particular storage element in the set of series-connected storage elements; (b) subsequently, performing program and verify operations on the adjacent storage element to raise a threshold voltage of the adjacent storage element; (c) subsequently, performing further program and verify operations on the particular storage element to raise the threshold voltage of the particular storage element to a second verify level, above the first verify level, and during the further verify operations, applying a second pass voltage, which differs from the first pass voltage, to the adjacent storage element.
