Description

Description: TECHNICAL FIELD The present invention relates to a memory with revision management information, and more particularly to a memory mounted on a cash processor.

Conventional technology Generally, CD (Cash Dispenser), ATM (Automatic Tell
A plurality of ROMs in which information such as data and programs are written are mounted in a cash processing machine such as an er Machine. In addition, due to design changes such as device functions and specifications,
Each ROM is often independently revised.

However, as a revision (revision) management method for each ROM, a method of writing the information of the revision number in each ROM is generally used. There is a drawback that it is very troublesome because the user has to refer to the documents.

In other words, despite the fact that the revision numbers of the ROMs to be combined differ depending on the function of the device, each ROM is revised independently, so there is no guarantee that the ROMs are implemented in the correct combination. There was a drawback that there was no simple system.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional disadvantages, and an object of the present invention is to provide a memory with revision management information having valid information for checking a combination with another ROM. It is.

Structure of the Invention A memory with revision number information according to the present invention is a memory mounted together with another memory, the revision number information indicating the revision number of the storage contents of the memory, and the memory at the time of revision of the memory. Revision version information for all other memories, and revision number information indicating the revision number of all implemented memories, and these revision number information are independent of the other memories. It is characterized by being updated.

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

FIG. 2 is a schematic configuration diagram of a cash processing machine as an example of a device equipped with a memory according to the present invention. In the figure, the cash processing machine 20 includes a control unit 10.

The control unit 10 includes a plurality of memories according to the present invention in which information such as data and programs is written. Here, in the present example, these memories are assumed to be three ROMs (Read Only Memory) for simplicity, and FIG. 3 shows an embodiment thereof. FIG. 1 shows a state in which ROMs 1, 2, and 3 are mounted on the control unit 10.

Each ROM is mounted on the control unit 10 via a socket or the like so that it can be detached independently. Each ROM is independently revised in accordance with a change in the specifications of the device.

Here, although the combination of the ROMs is an important matter for the device, it has been conventionally checked using documents or the like as described above. In contrast, according to the present invention, every time each ROM is revised, all other ROs are stored in the ROM.
The information on the revision number of M and the total number of revisions for all ROMs is written, and these are read out and checked by software. Thus, the check can be performed without using documents or the like.

Next, information written in each ROM will be described with reference to FIG. FIG. 1 is a table showing an example of the stored contents of each of the ROMs 1 to 3 in FIG.

In the figure, the total revision number is information whose value is increased each time each ROM is revised. That is, the ROM with the largest revision number is the latest revision.

The revision number of the ROM 1 is information whose value is increased each time the ROM 1 is revised. That is, the revision number is updated each time the storage content of the ROM 1 is rewritten. Similarly, the revision number of ROM2 is information whose value is incremented each time ROM2 is revised, and the revision number of ROM3 is information whose value is incremented each time ROM3 is revised.

Furthermore, the information in a row in the figure is the original data,
This is information written to each ROM in addition to programs and the like. That is, in ROM1, the above-mentioned total revision number is written as "01", the revision number of ROM1 itself is written as "01", and the revision numbers of ROM2 and ROM3 are respectively "0".
1 "and" 01 "This information was written when the storage contents of the ROM 1 were revised.

Similarly, ROM2 has an overall revision number of “02” and ROM
The first revision number is "01", the revision number of ROM2 itself is "02", and the revision number of ROM3 is "01". This information was written when the storage content of the ROM 2 was revised.

In addition, the number of the entire revision is “03” in ROM3,
The revision number of 1 is written as "01", the revision number of ROM2 is written as "02", and the revision number of ROM3 itself is written as "02". This information was written when the storage contents of the ROM 3 were revised.

Write the above information when revising each ROM,
If the information is read out by software, the latest ROM
, That is, whether or not each ROM is implemented according to the correct combination of ROMs.

That is, the storage contents of each ROM are sequentially read out, and among them, the one having the highest total revision number. According to the above example, the storage contents of the ROM 3 indicate the latest ROM combination, that is, the correct ROM combination. Become. So this ROM3
By examining the revision numbers of the other ROMs 1 and 2 based on the stored contents, it can be checked whether or not each ROM is correctly mounted.

Depending on the specifications of the device, the ROM used previously may be reused as it is at the time of revision. In such a case, the old revision number may be written as the new revision number of the ROM.

Further, it is apparent that the present invention can be applied to a system in which a single CPU is provided and read control of all ROMs is performed by the CPU, or a system in which a dedicated CPU is provided for each ROM.

Furthermore, the information on the revision is not limited to the serial number, but may be an alphabet or the like.

Effect of the Invention As described above, the present invention writes the own revision number and the revision numbers of other ROMs in each ROM, and each time the information of the entire revision number is revised,
By referring to these pieces of information, it is possible to easily check whether or not all the ROMs are mounted in a correct combination.
