ABSTRACT:
A fuse circuit may include a fuse cut detection unit to output state information indicating whether or not a fuse is cut during a fuse cut detection time period, a maintenance and output unit to maintain the state information and output a fuse state information signal, and a connection/disconnection unit to connect the fuse cut detection unit to the maintenance and output unit during the fuse cut detection time period and disconnect the fuse cut detection unit from the maintenance and output unit after the fuse cut detection time period. A fuse circuit may recognize an indefinite voltage at a detection node caused by a leakage path through a fuse as a predetermined fuse state.
