PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device which inhibits a nonvolatile memory from being written, read, and/or erased when a rewriting frequency is exceeded and guarantees the security of data of a program, etc., at the same time. SOLUTION: A counter control part 6 is provided which obtains a rewrite value by processing as specified the rewriting frequency of a counter 5 counting up or down each time the nonvolatile memory 3 is rewritten once and stores the rewrite value in a counter memory cell 7, and a memory control part 4 inhibits the nonvolatile memory 3 from being rewritten and/or read according to the rewrite value stored in the counter memory cell 7.
