ABSTRACT:
To provide a memory-writing device which can simply and reliably write desired data to a nonvolatile memory of an electronic device, connection is made with an ECU to perform write processing to write write data from the memory-writing device to a flash ROM by copying a write-control program from the external portion to a RAM and executing the write-control program, and by sequentially sending the foregoing write-control program and write data to this ECU together with sending, at a predetermined timing, write-control information required for the ECU to execute the write-control program, the write-control program and the write-control information are stored in a freely attachable and removable first ROM and the write-control information stored in the first ROM is read and sent to the ECU at a memory-rewriting device.
