Abstract
A storage device for verifying whether memory cells have been programmed. The storage device may be configured to use a verification technique, that is part of a set of verification techniques, to verify data states of a set of memory cells of a selected word line. The one or more verification techniques may be utilized based on an iteration of the verify operation that is to be performed. The storage device may be further configured to perform, using the verification technique, a next iteration of the program-verify operation to verify whether one or more memory cells have been programmed. Using the verification technique and performing the next-iteration of the program-verify operation are to be repeated until the set of memory cells have been verified.
