摘要： 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 program the memory cells in a program operation. During the program operation, the control means programs the memory cells connected to at least one particular word line of the plurality of word lines using a first programming technique while programming the memory cells connected to plurality of word lines other than the at least one particular word line using a second programming technique different than the first programming technique.
