摘要：A fuse circuit uses an electrically writable fuse circuit and comprises a first fuseunit provided with a first electrically writable fuse, and a second fuse unit provided with a

second electrically writable fuse, and the state of logical add of the states of the first andsecond fuse units is used as the output of the electrically writable fuse circuit in the firstand second fuse units. Reliability in writing in of the fuse can be improved by using such afuse circuit for a redundancy decoder circuit or the like.
