Abstract
A control circuit connected to non-volatile memory cells applies a programming signal to a plurality of the non-volatile memory cells in order to program the plurality of the non-volatile memory cells to a set of data states. The control circuit performs program verification for the non-volatile memory cells, including applying bit line voltages during program verification based on word line position and data state being verified.
