<p>PURPOSE:To increase a contact reliability and to easily attain the data writing to a ROM by directly sticking the ROM to a memory substrate different from muP, connecting the same type of the substrate as the memory substrate to a ROM writer as a repeating substrate and executing the data writing to the ROM. CONSTITUTION:A microprocessor (muP) substrate 2 and a memory substrate 1 are always electrically connected and operated, and at the time of the data writing of a programmable reading exclusive-use memory (ROM)3, the muP substrate 2 and the memory substrate 1 are separated, the memory substrate 1 and a repeating substrate 11 are electrically connected, the repeating substrate 11 and a memory writing device 10 are electrically connected and writing is executed to the ROM3. By using the repeating substrate 11 having the same type of the wiring pattern as such a memory substrate 1, the connection of a cable 12 at the time of connection with a ROM writer 10 can be easily performed. Thus, the contact reliability is increased and the data writing to the ROM can be easily executed.</p> |
