Abstract: For rewriting data, which includes programs, stored in a programmable ROM, a receiving-side information processing apparatus first transfers a reception program included in the data stored in the ROM to a RAM. Control jumps to the reception program stored in the RAM, whereby reception is executed. Received data is written in the ROM according to the program stored in the RAM. The programs stored in the ROM can thus be rewritten.
