Abstract
PURPOSE:To improve a success rate in the substitution of a defective address for a redundant address by a method wherein a substitution fuse has a plurality of pieces of serially connected cutting fuse parts. CONSTITUTION:Cutting fuse parts 2 are connected in series two pieces and are installed in a substitution fuse 1 which is extended unidirectionally and two pieces of the fuse parts 2 in the fuse 1, which is intended to cut at the time of cutting of the fuse, are all cut. If at least one cutting fuse part 2 out of them is cut, it means that the fuse 1 has been cut.
