Abstract

PURPOSE:To attain the write of a proper code on an EEROM with a simple system as a whole by transferring a written content on a PROM to a mounting EEPROM using a PROM loader. CONSTITUTION:The proper code is written on a PROM2 using a general purspose PROM writer 1. At the next, the PROM2 after the write is inserted to a PROM loader 5 and the loader 5 is connected to an equipment 3 in which the EEPROM is built in, transferring the data. Therefore, for example, by installing an expensive PROM writer at a center, arranging an inexpensive PROM loader at local areas, a cheap writing system for the proper code can be constituted as a whole.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a unique code writing method for writing a unique code of a mobile telephone or the like into the memory of a device.

The unique code for a car phone includes its car phone number, device number, area number, etc., and these are written in a 32-byte memo IJ (PROM) of the mounted device and used.

[Conventional technology]

Traditionally, to set this type of unique code on a device, PR
OM was used. In this case, the PROM is written using a dedicated PROM writer, and the written PROM is pushed into the specified location of the device by opening the lid of the device.
It was unreliable. However, when the EEPROM was developed, a device was created that sent a unique code to the device through an external signal line and wrote it into the built-in EBPFLO without opening the lid.

Conventionally, when writing a unique code to a device that has a built-in ROM, the control device such as a personal computer must be
Connect to a device with built-in ROM, transfer the unique code directly to the control device such as a personal computer, and transmit this signal to the EBPR.
EEPROM by the program of the device with built-in OM
I was writing to.

[Problem that the invention seeks to solve]

Although this conventional writing method is an efficient method,
It is completely incompatible with equipment that used PROMs and used unique codes before using EPROMs. In order to write a unique code using this PROM, a dedicated PILOM programmer is used to write the PROM, and this PROM is inserted into a device for use. in this case,
PROM writers have built-in software that makes it easy for people to input operations, so they are easy to use but expensive.

On the other hand, when using an EEPROM, there is a problem in that a new control device such as a personal computer must be provided. Control devices such as computers must have built-in software that makes it easy to input operations, but control devices such as computers are extremely expensive, and if conventional methods were used, expensive equipment would be needed again. There was an interim period when we had to introduce .

The conventional writing method using a PROM writer is
Shown as shown. In the figure, 1 is a PROM writer, 2 is a PROM, and 3 is a mounting device for PROM2. This PR
The OM2 is inserted into the PROM writer 1, has a unique code written therein, and is mounted on the device 3.

In addition, it is also possible to perform EE of the equipment directly using a control device such as a PC.
The case of writing a unique value to PROM is shown in FIG. That is, a control device 4 such as a personal computer is directly connected to the device 3 and a unique code is written in the BEPROM 2. In these cases, there were problems as described above.

The purpose of the present invention is to solve such problems, to be compatible with conventional writing methods, and to write B without introducing expensive equipment.
An object of the present invention is to provide a unique code writing method that can write a unique code to an EPROM.

[Another way to solve the problem]

In a unique code writing method that allows the IPR (JM) to write the unique code of this device to the IPR implemented in the device, the component company of the present invention writes the unique code to a specific PR using a PROM writer.
Write to OM and write the written contents to this PROM.
It is characterized in that the data is transferred to and loaded into the mounted EEPROM using a loader.

〔Example〕

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing a writing method according to an embodiment of the present invention. In the figure, the same numbers as in FIGS. 2 and 3 indicate the same components, and 5 indicates a PROM loader.

This unique code is conventionally written into the PROM 2 using the general-purpose PROM writer 1. Next, the written PROM 2 is inserted into the PROM loader 5, the PROM loader 5 is connected to the device 3 containing the BEPROM 2, and the data is transferred. According to this method, a PROM loader 5 is required compared to the conventional method, but since the PlaOM loader 5 only reads the PROM 2, it can be configured with simple hardware such as a chip (chip) or CPU, and a personal computer, etc. The control device 4 can be constructed from a very inexpensive device compared to the control device 4 shown in FIG.

For example, if you install an expensive PROM writer at a center (head office), place an inexpensive PROM loader at a local area (branch), and create PROMs at the center and ship them to each location, the unique code will be cheaper overall. A writing system can be configured.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to use the dedicated ROM writer that has been used in the past, and it is also possible to write a unique code into a device with a built-in EEPROM without opening the lid. , it is possible to construct an inexpensive system as a whole.
