Abstract
A memory apparatus and method of operation are provided. The apparatus includes memory cells connected to word lines and disposed in memory holes coupled to bit lines. A control means successively applies each of a series of pulses of a program voltage to selected ones of the word lines while simultaneously applying one of a bit line program voltage and a bit line inhibit voltage to ones of the bit lines coupled to the memory holes containing groups of the memory cells connected to the selected ones of the plurality of word lines to program the groups of the memory cells with data. The control means maintains a voltage applied to ones of the plurality of bit lines as the bit line inhibit voltage in response to the ones of the plurality of bit lines remaining unselected when programming a next one of the groups of the memory cells.
