Abstract
A memory apparatus and method of operation are provided. The apparatus includes memory cells connected to word lines and configured to retain a threshold voltage corresponding to one of a plurality of data states. A control means ramps up and applies a read voltage to unselected ones of the word lines while applying verification pulses of program verify voltages each associated with one of the plurality of data states to selected ones of the word lines to determine whether the memory cells connected thereto have the threshold voltage above each of the verify voltages associated with the plurality of data states targeted during a program-verify operation. The control means delays ramping of at least one of the selected ones of the word lines and the unselected ones of the word lines by a predetermined period of time in response to the memory apparatus operating in a predetermined mode.
