Abstract
An apparatus is provided that includes a plurality of non-volatile memory cells and a control circuit coupled to the non-volatile memory cells. The control circuit is configured to perform a first program-verify iteration on a first set of non-volatile memory cells coupled to a first word line to determine a first starting program voltage that programs the first set of the non-volatile memory cells to a first programmed state, and program a second set of non-volatile memory cells coupled to the first word line beginning with the first starting program voltage only if a defect condition does not exist.
