and an electronic control unit that is configured to write information to the memory in accordance with the writing program stored in the memory, wherein: the memory stores a disabling program for disabling overwriting of the information stored in the memory, the electronic control unit disables overwriting of the information stored in the memory in accordance with the disabling program stored in the memory for disablement when writing of the information executed by the electronic control unit is finished, the memory stores reference information to be referred to when the electronic control unit executes writing of information, and the electronic control unit overwrites the reference information stored in the memory with information that is unrelated to the reference information. ## Claims ### Claim 1 An information processing apparatus comprising: a memory that is configured to store written information and to store a writing program for writing information to the memory; and an electronic control unit that is configured to write information to the memory in accordance with the writing program stored in the memory, wherein: the memory stores a disabling program for disabling overwriting of the information stored in the memory, the electronic control unit disables overwriting of the information stored in the memory in accordance with the disabling program stored in the memory for disablement when writing of the information executed by the electronic control unit is finished, the memory stores reference information which is information to be referred to when the electronic control unit executes writing of information, and the electronic control unit overwrites the reference information stored in the memory with information that is unrelated to the reference information. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein the electronic control unit overwrites the writing program with information that is unrelated to the writing program. ### Claim 3 (depends on 1) The information processing apparatus according to claim 1, wherein the electronic control unit automatically disables overwriting of the stored information when writing of information executed by the electronic control unit is finished. ### Claim 4 (depends on 1) The information processing apparatus according to claim 1, further comprising: a communicator that is configured to: send out the stored information or production information produced based on the stored information to an outside when writing of information executed by the electronic control unit is finished; and receive a disablement instruction for disabling overwriting of the stored information after the communicator has sent the stored information or the production information, wherein the electronic control unit disables overwriting of the stored information when the communicator receives the disablement instruction. ### Claim 5 (depends on 1) The information processing apparatus according to claim 1, wherein communication between a plurality of outside electronic control apparatuses that control the electronic control apparatus is relayed. ### Claim 6 An information processing system comprising: an information processing apparatus that processes received information; and an information communication apparatus that sends information to the information processing apparatus, wherein the information processing apparatus includes: a writing program for writing information to the memory; and an electronic control unit that is configured to write information to the memory in accordance with the writing program stored in the memory, wherein: the memory stores a disabling program for disabling overwriting of the information stored in the memory, the electronic control unit disables overwriting of the information stored in the memory in accordance with the disabling program stored in the memory for disablement when writing of the information executed by the electronic control unit is finished, the memory stores reference information which is information to be referred to when the electronic control unit executes writing of information, and the electronic control unit overwrites the reference information stored in the memory with information that is unrelated to the reference information. ### Claim 7 (depends on 6) The information processing system according to claim 6, wherein the information processing apparatus further includes a communicator that is configured to: send out the stored information or production information produced based on the stored information to the information communication apparatus when writing of information executed by the electronic control unit is finished; and receive a disablement instruction for disabling overwriting of the stored information after the communicator has sent the stored information or the production information, the information communication apparatus includes: a second communicator that is configured to receive the stored information or the production information; and a second electronic control unit that is configured to determine whether or not overwriting of the stored information is disabled based on the stored information or the production information received by the second communicator when the second communicator receives the stored information or the production information, wherein: the second communicator sends the disablement instruction to the information processing apparatus when the second electronic control unit determines that disablement is executed, and the first electronic control unit disables overwriting of the stored information when the communicator receives the disablement instruction.
