Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 2:
3. The non-volatile storage apparatus of claim 1, wherein:
each regular control gate driver of the set of regular control gate drivers receives multiple different sources of voltage and comprises multiple voltage paths including a different voltage path connected to each of the received multiple different sources of voltage; and
the control circuit is configured to test the set of regular control gate drivers by:
separately testing each voltage path of each regular control gate driver of the set of regular control gate drivers by driving a respective source of voltage through the respective voltage path and comparing an output for the respective control gate driver to an upper reference voltage and a lower reference voltage for each voltage path of each regular control gate driver of the set of regular control gate drivers, and
determining that a particular regular control gate driver of the set of regular control gate drivers is defective because if an output for the particular regular control gate driver is either above the upper reference or below the lower reference when driving at least one source of voltage through at least one of the voltage paths for the particular regular control gate driver.
