A memory apparatus and operating method are provided. The apparatus includes memory cells connected to word lines and disposed in memory holes and configured to retain a threshold voltage. The memory holes are organized in rows grouped in strings and the strings comprise a plurality of blocks which comprise planes. A control means is configured to program the memory cells connected to one of the word lines and associated with one of the strings in each of the plurality of planes and acquire a smart verify programming voltage individually for each of the planes in a smart verify operation. The control means concurrently programs at least some of the memory cells connected to each of the word lines in each of the planes in a program operation using the smart verify programming voltage individually acquired for each of the planes in the smart verify operation.
A memory apparatus, comprising:
A controller in communication with a memory apparatus including memory cells connected to one of a plurality of word lines and disposed in memory holes and configured to retain a threshold voltage corresponding to one of a plurality of data states, the memory holes organized in rows grouped in a plurality of strings, the plurality of strings comprise a plurality of blocks comprising a plurality of planes, the controller configured to:
