PROBLEM TO BE SOLVED: To provide a voltage setting circuit and a voltage setting method, for performing correction of setting voltage after packaging with high accuracy and high yield by using a fuse for writing of bit data to a storage means and appropriately determining whether blowout of the fuse is performed or not, and a semiconductor integrated circuit device using the same. SOLUTION: The circuit includes the storage means 10 which stores bit databased on a setting voltage by electrically blowing down a fuse MF provided in conformation to each bit based on the bit data; a blowout determination circuit 20 which determines whether the fuse MF is electrically broken by blowout or not, and outputs the determination result as serial data; a latch circuit 30 which temporarily stores the serial data output from the circuit 20, converts and outputs the data as parallel data; and a resistance value setting circuit 50 which sets a resistance value to output the setting voltage based on the parallel data.
