ABSTRACT:
A semiconductor device has a fuse, an internal circuit and a protection capacitor. The fuse has a first terminal connected to be applied to a fixed voltage and a second terminal. The internal circuit includes a transistor. The transistor has a threshold voltage and a gate. The protection capacitor is connected between the second terminal of the fuse and the gate of the transistor. The protection capacitor supplies the threshold voltage to the transistor where the fuse supplies the fixed voltage to the protection capacitor.
