Abstract
A memory apparatus includes memory cells connected to word lines and configured to retain a threshold voltage corresponding to data states. A control means is configured to erase the memory cells in an erase operation. The control means is also configured to apply each of a series of programming pulses of a program voltage followed by verification pulses of a plurality of program verify voltages each associated with one of the data states to selected ones of the word lines to program and verify the memory cells connected thereto during a program operation. At least one of the plurality of program verify voltages is adjusted for the memory cells connected to one or more defective ones of the word lines in response to an erase verify of the erase operation failing for the memory cells connected to the one or more defective ones of the word lines.
