1. A non-volatile storage apparatus, comprising:

  • a plurality of non-volatile memory cells; and

    one or more control circuits in communication with the memory cells, the one or more control circuits configured to program the memory cells and verify the programming;

    to verify the programming the one or more control circuits are configured to apply one or more voltages to perform boosting of a channel region associated with an unselected memory cell, allow the boosting of the channel region for a portion of time while applying the one or more voltages, temporarily prevent an increase in the boosting of the channel region while applying the one or more voltages for a duration of time based on position of a memory cell selected for verification, apply a compare signal to the memory cell selected for verification and the unselected memory cell, and perform a sensing operation for the memory cell selected for verification in response to the compare signal.
