Abstract

PURPOSE:To cancel the complicatedness of operation, and in addition, to shorten reading and writing time so that an information sharing system not to give a user an unpleasant feeling by sharing information by common memory spaces consisting of non-volatile memories. CONSTITUTION:When an A or B terminal system 1 or 2 is selected by software or hardware, the information corresponding to it is issued from a system selection circuit 8, and an address conversion circuit 9, 10 corresponding to one side is selected. One of memory maps 3, 4 is realized by this address conversion circuit 9, 10. Since the memory maps 3, 4 are added with rewritable non-volatile memory spaces 5, 6, they can be accessed even when the system is switched, and the memory map 3, 4 is changed. For instance, when the user dictionary or the learnt result of a Japanese language FEP is read and written from/to the non-volatile memory spaces (memory area) 5, 6, operation and time for storing it in an external storage device become unnecessary, and operability is improved remarkably.

In this figure, when a conventional terminal system (word processor / personal computer) having storage media of different specifications is to be incorporated into an information sharing system while maintaining the compatibility of the terminal systems, for example, It is a general method to deal with both aspects of software and hardware so that floppy disks of different formats can be read and written as a common external storage medium 511.

[0008]

However, in an information sharing system, for example, when a floppy disk is adopted as a common storage medium for shared information, the recording formats generally adopted by the respective systems are different, and therefore common It is necessary to prepare means for reading and writing. In addition, there are many problems that are obstacles to implementation, such as complicated replacement of floppy disks and unpleasant feeling to the user for the processing time of reading and writing data.

For example, in the case of an information sharing system of a word processor and a personal computer, Japanese input FE
P is an indispensable program for both parties and there are many parts that can be shared. In such a case, if a floppy disk is adopted as a common storage medium, the usage of software / hardware is generally different. Therefore, it is necessary to support both software / hardware and read / write from both terminal systems. In this case, swap the floppy disk every time you read or write shared information, or
It is necessary to occupy a floppy disk.

The present invention has been made in consideration of the above circumstances. In the information sharing system, an external storage medium such as a floppy disk is not used for sharing information, but a common memory space composed of a non-volatile memory is used. By sharing information, the complexity of operations is eliminated, and by using a semiconductor memory as a common storage medium, an information sharing system that shortens read / write time and does not cause user discomfort is provided. is there.

Therefore, in the information sharing system, the operability is improved as compared with the case where an external storage medium is used as the storage medium for shared information, and the user can use it without being aware of its existence.
