Abstract
Apparatus and methods are described to program memory cells and verify stored values programmed into the cells. The next stage in stored memory can be moved to the current verification iteration when certain conditions are met. Verification can include counting bits that exceed a voltage value for a stage being verified to produce a bit count number and determining if the bit count number for the stage being verified meets a threshold value. If the bit count number does not meet the threshold, the verification process can continue with a current verify iteration and thereafter move to a next verify iteration. If the bit count number does meet the threshold, the process can add a next stage to the current verify iteration and thereafter move to a next verify iteration.
