ABSTRACT:
A semiconductor device is provided as a fuse option circuit. The semiconductor device is configured to include an input, a function selection fuse portion and a reset control circuit portion both connected to the input, and an output connected to the function selection fuse portion. The function is switched by cutting off a first fuse included in the function selection fuse portion. In addition, by cutting off a second fuse included in the reset control circuit portion, the function of the fuse option circuit can be retrieved to the function that the first fuse is not cut off. Therefore, the productivity is the same as a bonding fuse method, and the chip area can be smaller than the chip area obtained by using the bonding option scheme.
