SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit which can be used as a product without altering a mask by reducing the time required for analyzing troubles of an LSI due to a voltage drop significantly. SOLUTION: The semiconductor integrated circuit comprises a voltage drop detecting circuit 200 for detecting erroneous operation due to a voltage drop, and a voltage regulating circuit 300 for elevating the voltage at the voltage drop part stepwise when the voltage drop detecting circuit 200 detects a trouble.
