Abstract
By switching a mode signal, capability of a drive circuit in a latch circuit can be improved than in a normal mode. Accordingly, even if a small leakage occurs in a blown portion of a fuse element, blow is correctly identified. In this manner, by improving drivability of the latch circuit, incorrect determination of fuse blow state can be avoided. Thus, a semiconductor device unlikely to make incorrect determination of fuse blow state can be provided.
