Abstract
A memory apparatus includes memory cells connected word lines. The memory cells are configured to store a threshold voltage corresponding to data states and are disposed in memory holes coupled to bit lines. A control means is configured to apply program pulses to selected ones of the word lines. Following each of the program pulses and for each one of the memory cells, the control means determines whether the threshold voltage of the one of the memory cells detected exceeds a lower verify level and a higher verify level of one of the data states targeted while applying one of a plurality of verify bit line voltages to ones of the bit lines coupled to the memory cells being programmed. The one of the plurality of verify bit line voltages is selected based on the threshold voltage of the one of the memory cells.
