Abstract
A semiconductor integrated circuit device includes a storage unit arranged on a semiconductor chip to store a plurality of data, and a plurality of registers provided on the semiconductor chip, the registers storing the data transferred from the storage unit, respectively. The storage unit has a nonvolatile memory element section and a volatile memory element section. The nonvolatile memory element section includes an address area which stores identification information of the registers as addresses and a data area which stores the data to correspond to the addresses by varying electrical characteristics irreversibly. The volatile memory element section temporarily stores the data read from the nonvolatile memory element section.
