ムを入力し、配憶させていた。[Detailed Description of the Invention] The present invention relates to a method for preventing program theft in electronic devices using microprocessors such as games such as video games, pachinko, and game watches. For easy replacement, all glograms were input and stored in the PI ROM.
しかしこれではそのロムをマスクとしてロムライターに
かけることによりプログラムを容易に複製できるので、
盗癲され易かった。However, with this, the program can be easily duplicated by using the ROM as a mask and applying it to the ROM writer.
It was easy to steal.

その複製を困廟ＫＬ、その盗廟を防止するものである。The present invention is designed to prevent such programs from being stolen, and by having two volatile users input a part of the program, it is difficult to copy the program, thereby preventing the theft of the program.
以下図面につき本発明の一実施例を詳細に説明する。An embodiment of the present invention will be described in detail below with reference to the drawings.

IQ~30 volatile RAMs 15 and 6 are power supply lines, respectively, and 6 is the same switch.Since these are the same as those of the conventional device, a detailed explanation will be omitted.

接続する。In the present invention, apart from the above-mentioned 2-piece 4, there is further provided a single-shot coil 7 with a small standby current.
- A battery 9 is connected to the resistor 7 through a resistor tjL8, and this resistor 8 is connected to the power supply line 5 through a diode IO.

電流は切れることがない。In this device, the program is input to the ROM 3, but not all of it is input, but an arbitrary one at that address is extracted and a part of it is input to a part of the ROM 7. The log 2m input to this ram 7 is performed by the writing device 11 at the time of shipment.Since the voltage of the battery 9 is always applied to this ram 7, the voltage vOC of the power supply im5 is set to 0 by turning off the switch 6. Even if this happens, the memory of the ram 7 will not be erased, and furthermore, since the battery 9 is charged through the diode IO during use, its current will never run out.

るものである。Therefore, even if a thief removes this ROM 3 from the device and copies the program, there is no point in copying the program because part of the program is missing. If it is removed, the current from the battery 9 will be cut off, so the memory will be erased and replication will no longer be possible. Also, even if I tried to copy the program with the ROM 3 and RAM 7 of this device installed in the device, I would be unable to find the address of the program 2 assigned to the RAM 7, so I would not be able to duplicate it. Since something other than the program on RAM 7 is always running, it is difficult to distinguish the address of the program on RAM 7 from other addresses, which makes it even more difficult to find, and it takes a lot of money and time. , becomes economically meaningless. Therefore, copying or theft of the program can be prevented.
