PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit and a redundancy system having a function of detour of fuse data in which transfer of fuse data from the fuse latch circuit is performed, but transfer of fuse data (data output) from the fuse box to the outside is not performed, thereby convenience is improved. SOLUTION: The semiconductor integrated circuit device comprises: a fuse latch circuit 12 for latching fuse data; a fuse counter 13 circuit; and a control circuit 15 including a transfer circuit 16 for transferring the fuse data to the outside, and a detour data path circuit 17 which does not transfer the fuse data to the outside and forms a detour data path for detouring the fuse data in the circuit itself when the fuse data is not transferred. In the fuse box 11, upon receipt of a control signal transmitted from the fuse counter circuit, the detour data path circuit 17 causes the fuse counter circuit 13 to operate a request signal for requesting the next fuse data from the fuse latch circuit.
