ABSTRACT:
An operating current is supplied from a power supply node to an internal circuit. In a test mode, current supply from a power supply to the power supply node is stopped by a current switch, and an externally adjustable test current is supplied to the power supply node. The test current is set in accordance with an acceptable value of a leakage current in the internal circuit. Evaluation is made as to whether the leakage current in the internal circuit is not greater than the acceptable value, in accordance with an output of a voltage comparison circuit detecting a voltage drop at the power supply node.
