As shown, a format conversion for converting input word data to match the storage format of the word record table storage unit 106 of the foreign language word learning apparatus. Unit 100; A memory 102 for storing word data converted from the format conversion unit 100; The display control unit 108 controls the display unit 110 to read the word data stored in the memory 102 and display the word data stored in the memory 102 according to the control signal of the memory control unit 104.

2 shows a memory structure of a foreign language word learning apparatus. As shown in FIG. 2, a TIO (Table of Content) region and a data region in which actual data are stored are shown. Here, the TOC area is composed of a file management table (hereinafter, abbreviated as “FAT”) containing information on the location and attributes of the files recorded in the TOC information area and the data area. It exists over a block of.

Each file recorded in the data area also has a word record in which information on a plurality of foreign language words is recorded. That is, as shown in FIG. 4, the word record is configured to record each code value displayed by encoding words, meanings, synonyms, examples, and interpretations of predetermined data, their number of bytes, parts of speech code, and word information. do.

FIG. 3A is a format display diagram showing the TOC information area in the memory structure of FIG. As shown, an ID indicating a unique number or version of a model of a foreign language learning device, a number of stored files indicating a number of files stored in a memory of a foreign language learning device, a blank block table indicating a block state of a memory; It is composed of a reserve area that is reserved for new format information.

FIG. 3 (b) is a format display diagram showing each file information recorded in the FAT area. As shown, the name of the file, the number of blocks occupied by the file, the block ID in which the data of the file exists, It consists of the number of words in the file in binary number, and the reserved area.

The operation of the present invention configured as described above will be described in detail with reference to FIGS. 1 to 4 as follows.

First, in the present invention, when predetermined data is input as shown in FIG. 1, the system controller (not shown) converts the data into a storage format of the word record table storage unit 106. The memory 102 stores the data in the memory 102 via.

That is, when data is stored in the memory 102, it is converted into the format as shown in FIG. 4 and stored.

For example, when English word “Boy” is input to a foreign language learning apparatus, the system controller converts the data into a word record format for “Boy”, and the data is calculated by a code value obtained through a constant encoding operation. The code value is stored in the word record table 106.

In more detail, after the “Boy” data is coded, words, meanings, synonyms, example sentences, and interpretation codes are calculated as code values capable of discriminating each piece of information, such as “001,010 to 101”, respectively. Code values such as “001,010 to 101” are stored in each item of the word record.

In this case, if a corresponding code and a field are added in addition to the word information illustrated in FIG. 4, the word information may be additionally recorded.

A plurality of word data input in this way is generated and stored in a file in memory. That is, the file includes a plurality of word data, and when the files are stored in the memory 102, the memory control unit 104 at the same time controls the information about the files to store in the TOC area.

In other words, when the corresponding data stored in the table in accordance with the word record format is stored in a specific file in the memory 102, the memory control unit 104 searches for the blank block table in the TOC information area. The blank block table indicates whether a plurality of blocks exist in a data area in a memory structure, and indicates whether data is stored in a corresponding block, or a state in which a block is empty or an error occurs. This display method of the blank block table is also recorded in the format diagram shown in FIG. 3 (a) using an identification code. For example, in the blank block table, if the data area of the memory 102 has 128 blocks, and data is not written in any one of the 128 blocks and is empty, it is “00”. If the data is stored, “FF” If the bad block (Bad Block) is an error occurs, it is displayed as "BB". Here, the bad block refers to a block area in which data error occurs due to a failure of a memory cell.

In this way, the memory controller 104 searches for the block and stores the corresponding file in the empty block. At this time, information about the file in which the word data is stored is also stored in the TOC area in the format shown in FIG. 3 (b). . At this time, each file TOC in the FAT area where information about the file is stored is equal to the number of files stored in the data area of the memory 102. That is, when n files are stored in the data area, information about the n files is stored in the file TOC.

Also, the memory controller 104 converts the word data stored in the memory 102 into a predetermined format and accesses the TOC area and the data area of the memory with each other, so that the empty block is not a block in which data is recorded or an error occurs. Locate and save the file in the corresponding block.

If any data is input in this way, the foreign language learning device converts it into the format of the word record and stores it in the data area in the memory 102. At this time, each file exists over a plurality of blocks. That is, if the size of a predetermined file is 15Kbyte and the size of one block is 4kbyte, it exists over four blocks. If the file size and the block size do not match, the file is left blank.

On the other hand, when the word data stored in the specific file of the memory 102 is to be displayed on the display unit 110, the system controller searches for the TOC area in the memory 102 and has information about the location and attributes of the file. Access files in the data area.

That is, as shown in FIG. 2, in the case where it is desired to read the information on the file 2 spanning the blocks 5 and 6, the system controller first searches for the information on each file of the FATt area. At this time, the information about the file 2, that is, the name of the file 2, the number of blocks occupied by the file, the number of words stored in the file and the ID of the blocks occupied by the file are read, and the word data to be searched is accessed. Display the data.

On the other hand, the rib areas in FIGS. 3A and 3B are reserved areas for newly added format information.

As described in detail above, according to the present invention, after determining a storage format of data stored in a memory, foreign language word learning is performed by storing word data in a specific file of the memory or reading word data stored in the memory according to the format. There is an effect that can effectively control the memory of the device.
