SEMICONDUCTOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit capable of a high-reliability circuit operation by suppressing electric charges to be discharged from a holding node via the parasitic capacitance of fuse wirings.

SOLUTION: The semiconductor integrated circuit has an internal circuit 200, a fuse circuit 20 for setting the circuit operation of the internal circuit 200, and a protective capacitance 30 to be coupled capacitively to the parasitic capacitance C1 of the fuse circuit 20. This semiconductor integrated circuit is provided with a latching circuit 10 for holding a signal FINT to be made to propagate to the internal circuit 20.
