Abstract
A memory apparatus and method of operation are provided. The apparatus includes memory cells each connected to one of a plurality of word lines and disposed in memory holes. The memory cells are configured to retain a threshold voltage corresponding to one of a plurality of data states. A control means is coupled to the plurality of word lines and the memory holes and is configured to identify at least one grouping of the memory cells to be programmed with a multi-pass programming operation. The control means is also configured to program the at least one grouping of the memory cells using the multi-pass programming operation. The control means is additionally configured to program the memory cells other than the at least one grouping of the memory cells in a full sequence programming operation.
