1. A non-volatile storage device comprising:
a memory configured to store data in a non-volatile manner;
an A/D converter;
a power supply configured to generate an internal voltage to feed the internal voltage to the memory and to the A/D converter;
a controller configured to control the memory and the power supply; and
a fault detector configured to detect a fault related to data written in the memory based on an output of the A/D converter,
wherein the A/D converter is configured to perform A/D conversion on the internal voltage fed from the power supply to the A/D converter directly without passing through the memory.
