Abstract
In a fuse circuit including programmable fuses in a semiconductor integrated circuit, the fuses store specific information related to the semiconductor integrated circuit, such as redundancy information, wafer lot number, die lot number, and die position on the wafer, etc. The fuse circuit utilizes a plurality of fuses for storing identical bit information. Consequently, in the case where a fuse has not been cut out correctly, the fuse circuit can reduce programming defects, whereby defect generation rates are remarkably decreased.
