ABSTRACT:
Fuse data is supplied to each of a plurality of function blocks through a transfer path using shift registers. When the reliability of fuse elements is low, there is a possibility that a part of the fuse data may have an error. Further, when the transfer path of the fuse data is long, there is a possibility that a value of the fuse data may be inverted due to an influence of noises. Thus, a decoder is arranged in the transfer path of the fuse data, and encoded data is stored in the fuse elements. By performing error detection/correction in the decoder, the high reliability is assured with respect to chip operations and the like.
