Description

[Detailed explanation of the invention] <Industrial application field> This invention is a ROM (PROM, EPROM, EEPROM)
This relates to a system that writes data to a computer (such as a computer).

<Conventional technology and its problems> Traditionally, data writing with a ROM writer is
ROM writers input data directly by hand using their own keyboards, or by storing data created on another computer on paper tape, or by inputting data directly from an input port.

Also, online writing devices have been used that are equipped with a computer interface that allows desired data to be written directly from a computer.

Using various PROM writers like this,
For example, when data generated in a production factory was written to a ROM in a control room at the head office and saved, the paper tape, magnetic tape, ROM, etc. on which the data was recorded had to be transported or mailed. This was actually done.

However, transporting and mailing items in this way was irrational in terms of time and economy.

<Problems to be solved by the invention> The invention was created in view of the current situation as described above, and consists of a reader for reading object data, an input/output device for writing and calling data into ROM, and a data writing device. A semiconductor memory writer consisting of a memory for controlling calls, a CPU, etc. can entrust data with multiple other semiconductor memory writers, send and receive data to each other, and read and write data online. The present invention provides a semiconductor memory writer having such a transmitting/receiving means so as to be able to write data in a short time even over a long distance and to enable network communication.

<Examples> The present invention will be described in detail below using specific examples with reference to the drawings.

FIG. 1 is a block diagram showing a semiconductor memory writer in a factory A of a certain company and a block diagram showing a semiconductor memory writer in a head office management department.

The semiconductor memory writer is composed of an EP-ROM 1, an input/output device 2, a memory 4, a keyboard 6, a tape reader 7, a paper tape 8, a transmitting/receiving device 5 according to the present invention, and a CPU 3.

The paper tape 8 has recorded data to be written in the necessary ROM, and the tape reader 7 is for reading the data on the paper tape. In addition, the keyboard 6 is used for manually inputting data to be written to the ROM 1, transmitting data,
It is used to give instructions for reception, etc. Next, a program for transmitting and receiving data is recorded in the memory 4, and the CPU
3, according to instructions from the keyboard 6 and the received data,
It follows the data in the memory 4 and performs data transmission/reception commands and write control. EP-ROM
(ROM) 1 is to which desired data is written by a semiconductor memory writer, and is actually written thereto. And input/output device 2 is
This is a device that writes or reads desired data into the ROM 1 based on a signal from the CPU 3.

Here, a telephone line type transmitting/receiving device 5 showing an example according to the present invention is connected to the CPU 3 on one side and the transmitting/receiving device 5 of another semiconductor memory writer via a telephone line, and is connected to a so-called MODEM and other devices. It is composed of accessory parts. Note that the connection of such a semiconductor memory writer is 2
It is possible to communicate with multiple telephone lines, not only with one telephone, but with three or four telephones, and to perform network communication.

Let's assume that one semiconductor memory writer is installed at Factory A in Kansai, and another is installed in the management department of the head office in Tokyo, and the production control data from the factory is managed by the management department of the head office. explain.

Factory A produces printed matter, and each day,
Various production control data such as number of sheets to be processed, number of items, defective rate, cause of defective etc. are organized and controlled, and this production control data is recorded on paper tape 8 and transferred to the tape reader 7 of the semiconductor memory writer.
The data may be read by the computer and written into the ROM 1 by a desired process, or the data may be written into the ROM 1 by directly inputting the data from the keyboard 6.

That is, in this data writing, as shown in FIG. 4, data is first loaded from the data start address in S9 using the tape reader 7 in the case of a paper tape type, then address data is loaded in S10, and then the data is loaded in S11. Than
For data writing to ROM1, Vpp is applied for a specified time via the input/output device 2 to write sequentially, and when the address and increment data are loaded in S12 and S13, the writing is completed and END.
This is the result.

The data to be input may be entered manually from the keyboard 6, or another computer may be connected and the data from that computer may be imported online.

Next, the management data thus recorded in ROM 1 needs to be sent not only to the factory but also to the head office for management. Therefore, according to the present invention, data is transferred from the transmitting/receiving device 5 of the semiconductor memory at the factory side to the transmitting/receiving device 5 of the semiconductor memory writer at the head office through the telephone line, and is processed according to the desired process.
Data will be written to ROM1.

That is, the data transfer and writing via the communication line may be performed simultaneously with the data writing to the factory ROM 1, or the written data may be written to the ROM 1 and then transferred to the input/output device 2.
You can also read it and transfer it.

When transmitting data, as shown in Figure 3, first set the data to be transferred in the semiconductor memory side, and enter the telephone number of the other party using the keyboard 6.
No., by pressing the transfer switch, memory 4
The transmission program recorded in will start.
A signal is sent out from a transmitting/receiving device having a MODEM or the like that converts it into a signal for a telephone line, and it is determined in S5 whether the connection on the receiving side is OK by renewing the signal from the other party. If the answer is "YES" here and it is confirmed that the receiving semiconductor memory writer is connected, S7 will load the data one by one, and S8 will confirm that all the data has been loaded and the process will end. .

On the other hand, when the semiconductor memory writer on the reception side at the head office receives data from the line, as shown in Figure 2, when a signal from the transmission side is input in S11, the connection on the transmission side is confirmed, and the data is transmitted in S2. After receiving the data, the transmitting/receiving device 5
MODEME converts to normal signal mode,
In step S3, the input/output device 2 writes data to the ROM 1 under the control of the CPU 3 according to a program stored in the memory 4, and when the data reception is completed in step S4, the process ends.

In addition to this example, the device of the present invention can be used to call a semiconductor memory writer at the head office over a telephone line at a factory, and then call a semiconductor memory writer at another factory.
It is also possible to record to ROM, and by doing so, a complex network can be created and the management ability can be further improved.

<Effects> The present invention is as described above, and by providing a semiconductor memory writer with a transmitting and receiving function that can be updated with other semiconductor memories, data can be written in a short time even over long distances, and time and cost problems can be avoided. In addition, by doing this, network communication is performed, and it becomes possible to receive and write data from a necessary location when necessary, or to transfer and write data, which improves data management. It will be extremely good.
