Abstract:
Methods for program verifying a memory cell include generating an access line voltage in response to a count and applying the access line voltage to a control gate of the memory cell, and generating a pass signal in response to the access line voltage activating the memory cell. Methods further include comparing at least a portion of the count to an indication of a desired threshold voltage of the memory cell, and when the at least a portion of the count matches the indication of the desired threshold voltage of the memory cell, determining if the pass signal is present. Methods further include generating a signal indicative of a desire to inhibit further programming of the memory cell if the pass signal is present when the match is indicated.
