Classification: CPC G  H | IPC G  H

Claim 3:
4. The non-volatile storage apparatus of claim 3, wherein the control circuit comprising a testing circuit that is configured to test the set of regular control gate drivers, the testing circuit comprises:
a multiplexer circuit connected to each voltage path of each regular control gate driver of the set of regular control gate drivers;
a dynamically configurable voltage divider connected to an output of the multiplexer circuit, the voltage divider has a voltage divider ratio indicating the fraction of the voltage output;
a first comparator having a first input connected to an output of the voltage divider and a second input connected to the upper reference voltage; and
a second comparator having a first input connected to the output of the voltage divider and a second input connected to the lower reference voltage;
for each of the voltage paths, the control circuit is configured to dynamically adjust the voltage divider so that the voltage divider ratio varies to divide a respective voltage from a respective voltage path to be within the upper reference voltage and lower reference voltage if no defect exists for the respective voltage path.
