A semiconductor integrated circuit device has a redundancy circuit such that when a parallel/serial conversion circuit converts the separation information of a program element group such as one fuse element group to serial data, the serial data is transmitted through a serial/parallel conversion circuit, thus controlling circuits to be controlled such as a plurality of RAMs. Further by introducing a CRC technique in the parallel/serial conversion circuit, even when there is an error input such as cutting error of the fuse element, the information may be reproduced.
