Abstract
A memory apparatus and method of operation are provided. The apparatus includes memory cells each connected to word lines and disposed in memory holes. The memory holes are arranged in rows comprising strings which are grouped into blocks comprising a first plane and a second plane. A control means is configured to program memory cells of the first plane and the second plane connected to one of the word lines using iterations of a program operation. The control means terminates programming of the first plane prior to completing programming of the first plane in response to determining the first plane programs slower than the second plane by a predetermined number of the iterations of the program operation. The control means adjusts the predetermined number of the iterations based on an additional verify iteration performed on at least some of the memory cells beyond the iterations of the program operation.
