Abstract
A method for program verify is disclosed, such as one in which a threshold voltage of a memory cell that has been biased with a programming voltage can be determined and its relationship with multiple program verify voltage ranges can be determined. The program verify voltage range in which the threshold voltage is located determines the subsequent bit line voltage. The subsequent bit line voltage may be less than a previous bit line voltage used to program the memory cell.
