Abstract
An apparatus is provided that includes a plurality of word lines that include a plurality of word line zones, a plurality of non-volatile memory cells coupled to the plurality of word lines, and a control circuit coupled to the non-volatile memory cells. The control circuit is configured to determine a corresponding initial program voltage for each of the word line zones. Each corresponding initial program voltage is determined based on a number of program erase cycles.
