PROBLEM TO BE SOLVED: To provide a data processor, with which time for updating stored data is shortened by enabling efficient updating processing without requiring copy operation for every time of stored data updating, which is conventionally required, when updating the stored data to a nonvolatile memory. SOLUTION: A nonvolatile memory 1 and a volatile memory 2 for storing various data are connected to a control part 3 and a program memory 4 is connected to this control part 3. The program memory 4 stores various processing programs or various control programs and by operating the control part 3 on the basis of such a program, respective kinds of processing and control such as data write, read and updating are performed to the nonvolatile memory 1 or volatile memory 2. The volatile memory 2 internally secures a first storage region 5 for temporary storage for temporarily storing data to be updated to the nonvolatile memory 1 and a second storage region 6 for temporary storage to be used when updating data on the nonvolatile memory 1. |
