Abstract
A block of non-volatile memory cells is divided into a first sub-block and a second sub-block. Programming non-volatile memory cells of the second sub-block after programming non-volatile memory cells of the first sub-block comprises boosting unselected channels in the second sub-block to a boosted condition; prior to boosting unselected channels in the second sub-block to the boosted condition, boosting unselected channels in the first sub-block to the boosted condition to pre-charge the channels of the second sub-block; and applying a program voltage to a selected word line of the second sub-block while channels in the first sub-block are in the boosted condition and channels in the first sub-block are in the boosted condition.
