Or it relates to a data copy prevention device that can prevent the leakage of the data.

[Prior art]

Usually, computer systems record and read information at high speed and require a storage capacity, a microprocessor of a central processing unit connected to the main memory device for reading and processing a program or data from the main memory device, and an input / output device. And an input / output device for performing data transfer between the main memory and the main memory.

By the way, it has been known to use a non-volatile memory, which is a storage device that controls the microprocessor and its operation in configuring the digital electronic circuit of the controller in industrial equipment or process automation equipment.

In this case, the programs of the corresponding part recorded in the nonvolatile memory are one of the firmware technologies for controlling the operation of the microprocessor, and the technology plays an important part of the electronic circuit like the hardware technology. Since portions of the recorded firmware can often be illegally leaked through duplication, various countermeasures have been taken.

For example, one solution was to attach other hardware to the electronic circuitry, record special code in the hardware, recognize the code, and then execute the program.

However, even in the above cases, it is also possible to copy the program itself, and through copying and decrypting, the code in the separately attached hardware is released and the leak of the program cannot be guaranteed.

[Purpose of invention]

The present invention has been invented to solve the above-mentioned shortcomings, and together with the circuit arrangement of the surface mount on the socket for the integrated circuit to mount the microprocessor in which the non-volatile memory (ROM) or the memory is embedded in the corresponding board. By installing a high voltage generator on the floor and several connecting rods, it is intended to provide a data copy prevention device in a nonvolatile memory that can protect a program or data in the nonvolatile memory operated in an electronic circuit and prevent illegal leakage. There is a purpose.

[Configuration of Invention]

In the non-volatile memory data copy prevention apparatus of the present invention for achieving the above object, the non-volatile memory 8 is mounted on the socket 8 of the integrated circuit of the board 11, which is an electronic circuit board. The left and right surface mount parts 12 and 13 are installed in the socket 8, and a battery 1 and a high voltage generator 6 are respectively installed at the bottom thereof, and the nonvolatile memory 10 is disposed on the socket 8. It is characterized in that the two connecting rods 5 are installed and fixed, which causes the nonvolatile memory 10 itself to be damaged by an electric shock at the time of separation.

EXAMPLE

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view showing a non-volatile memory data copy prevention apparatus according to an embodiment of the present invention, the non-volatile memory data copy prevention apparatus of the present invention must be used to copy or illegally leak the program or data. The corresponding non-volatile memory 10, which is an integrated circuit, should be separated from the corresponding integrated circuit socket 8 of the board 11, which is an electronic circuit board. It can be solved by breaking it through electric shock.

That is, the socket for the integrated circuit 8 is mounted at the corresponding position on the board 11, which is the electronic circuit board, and the socket 8 is fixed on the board 11 by soldering. The nonvolatile memory 10, which is an integrated circuit, may be combined to perform a unique function.

In the socket 8 of the present invention, a battery 1 of a size small enough to be attached to the floor is provided, and a high voltage generator 6 for converting a low voltage of the battery 1 into a high voltage is also provided.

The left and right surface mount parts 12 and 13 are respectively provided on the socket 8, and thus, the resistor 2, the transistor 3, the diode 9, and the one connecting rod 12 are provided on the left surface mount part 12. 4), the other connection part 4 is each provided in the upper surface upper part loss part 13, respectively. In some cases, one to several hidden connecting tables 7 may be separately installed.

The nonvolatile memory 10, which is an integrated circuit corresponding to the socket 8, configured as described above is integrated.

Therefore, in the normal state, the connecting strips 4 and 5 or the hidden connecting strip 7 of the socket 8 are connected with the transistor 3 disconnected as shown in FIG. 3, and the high voltage generator 6 Since the power of the battery 1 is not applied, the original function of the nonvolatile memory 10 may be performed.

The diode 8 is provided to eliminate mutual interference between the nonvolatile memory 10 and the high voltage generator 6 in a normal operating state.

Accordingly, in the present invention, as shown in FIG. 2, the present invention is designed to prevent program leakage in the nonvolatile memory 10 mounted on the socket 8 of the door 11 and surrounded by two connecting rods 5. When the nonvolatile memory 10 in which a program is stored is disconnected from the socket 8 of the electronic board 11, a corresponding electric shock signal is transmitted from the high voltage generator 6 through the diode 9 to the non-volatile memory 10. Since it is applied to the data line of the volatile memory 10, the corresponding nonvolatile memory 10 is damaged at the moment of disconnecting the connecting strip (4, 5) or the hidden connecting strip (7) to prevent illegal copying and leakage of the program You can do it.

FIG. 3 is a circuit diagram for explaining a data copy preventing device in a nonvolatile memory of the present invention. When the data copy preventing device in the nonvolatile memory of the present invention is installed as shown in FIG. The non-volatile memory 10 in the socket 8 for the integrated circuit on wood 11 has a data line connected to the high voltage generator 6 via a diode 9 and a ground line connected to the high voltage generator 7 via a hidden connection 7. 6, an external connection 5 and a battery 1, respectively, the connection 5 is connected to the resistor 2 and the transistor 3 through the internal connection 4, respectively, the transistor 3 Are connected to the battery 1, the resistor 2 and the high voltage generator 6, respectively.

Therefore, according to the present invention, when the electronic circuit board is manufactured, measures and appropriate measures for preventing illegal copying or leakage of programs are appropriately taken, or safety measures (damage of nonvolatile memory which is not desired by the original manufacturer) are also taken. In order to illegally copy and leak the contents of the program of the nonvolatile memory 10, the internal and external connecting rods 4 must be separated when disconnected from the socket 8 of the board 11, which is a circuit board, as shown in FIG. Or 5) to block the herd connector (7).

At this time, if any one of the internal and external connection bands 4 and 5 or the hidden connection band 7 is broken, the low power of the battery 1 connected to the base of the transistor 3 is supplied through the resistor 2, so that the transistor (3) is turned on so that a low voltage is applied to the high voltage generator 6.

Therefore, when a low power source is applied to the high voltage generator 6, a high voltage damaging the nonvolatile memory 9 is applied to the data line of the nonvolatile memory 10 via the diode 9, and as a result, the nonvolatile memory 9. The memory 10 is broken at the moment of separation, and the program data therein cannot be recovered.
