Abstract
In a method for testing whether or not a fuse on a semiconductor substrate is disconnected, a first test operation is performed upon the fuse by determining whether or not a resistance value of the fuse is larger than a first threshold resistance value. Then, a second test operation is performed upon the fuse by determining whether or not a resistance value of the fuse is larger than a second threshold resistance value smaller than the first threshold resistance value.
