PROBLEM TO BE SOLVED: To reduce the size of a semiconductor integrated circuit device by considerably reducing the circuit area of a control information holding means which holds control information used for the trimming etc., of an analog circuit etc. SOLUTION: A fuse module 4 which holds the trimming information of an internal oscillating circuit module is composed of information writing fuse circuits 20<SB>1</SB>-20<SB>n</SB>in which the trimming information is written by fusing/non-fusing an information writing fuse 25, a reference fuse circuit 20 which discriminates whether the fuse 25 is fused or not, and a current/voltage converter 21. Since the reference fuse circuit 20 and current/voltage converting section 21 are commonly used for the information writing fuse circuits 20<SB>1</SB>-20<SB>n</SB>, the circuit area of the fuse module 4 can be reduced significantly.
