Abstract
Provided is a semiconductor integrated circuit device including a fuse circuit whose area and cost are minimized by a simple circuit configuration. The fuse circuit includes a first fuse and a second fuse having substantially the same shape and different sheet resistances, which are connected in series between terminals with different potentials. In a state in which none of the fuses is cut, a potential of an output terminal is fixed to a potential of one of the terminals.
