Abstract
A semiconductor integrated circuit comprises an electrically programmable fuse element that is provided between a programming voltage node and a latch node, and a latch circuit that latches a voltage at the latch node. The semiconductor integrated circuit further comprises a current source that controls a magnitude of an operation current of the latch circuit, and controls a resistance determination value for determining whether the fuse element is programmed or not.
