Abstract
A semiconductor device comprises a nonvolatile memory (A) for storing information on a frequency of operation; a volatile memory (B) in which the information on the frequency of operation is rewritten; and a control device for transferring the information on the frequency of operation stored in the memory (A) to the memory (B), rewriting the transferred information in the memory (B), and returning the rewritten information to the memory (A).
Claims6
