Abstract

A non-volatile memory includes memory cells, word lines connected to the memory cells, and a set of regular control gate drivers connected to the word lines. The control gate drivers include different subsets of control gate drivers that receive different sources of voltage and provide different output voltages. A redundant control gate driver, that receives the different sources of voltage and provides the different output voltages, is included that can replace any of the regular control gate drivers.
