Abstract
One fuse set is constituted of a plurality of fuse blocks. Each of the blocks includes a sub-fuse set constituted of fuse elements electrically programmable, and a program control circuit which controls programming of the fuse elements. One of the fuse elements is an enable bit representing validity/invalidity of the sub-fuse set. One fuse block becoming an object of the programming is determined in accordance with a value of the enable bit.
