Abstract
A memory apparatus and method of operation are provided. The apparatus includes memory cells connected word lines. The memory cells are disposed in strings and configured to retain a threshold voltage. A control means is configured to apply a program voltage to selected ones of the word lines while applying pass voltages to unselected ones of the word lines and ramp down both the selected ones of the plurality of word lines and the unselected ones of the word lines to a recovery voltage at a start of a verify phase of each of a plurality of program loops and apply a targeted word line bias to each of the word lines during the verify phase. The control means is also configured to adjust the recovery voltage based on the targeted word line bias applied to each of the plurality of word lines during the verify phase.
