Abstract
An apparatus includes a plurality of memory cells connected to word lines and bit lines and configured to retain a threshold voltage corresponding to one of a plurality of data states following a program operation; and a control circuit connected to the word lines and the bit lines. The control circuit is configured to use, during a setup clock of a loop of a plurality of loops of a program-verify operation, a first verify voltage ramping time period of a plurality of verify voltage ramping time periods based on a data state being verified during the loop, and use, during a setup clock of another loop of a plurality of loops of a program-verify operation, a second verify voltage ramping time period of the plurality of verify voltage ramping time periods based on a data state being verified during the other loop.
