Description

A new structure and method for quickly storing new data in phone memory {A DEVICE AND A METHOD OF NEW DATA SPEEDY MANAGING FOR TELEPHONE MEMORY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the rapid recording, storing and sorting of data using an EEPROM (Electric Erase Programmable ROM) having a relatively slow data transfer rate or drive rate for recording and reading data. It is a rapid management of the message storage address of the memory used for storing telephone numbers or messages.

In general, a telephone has a memory for storing a frequently used callee's unique telephone number and a simple message for identifying the number. Such a memory can store a large amount of data although the data transmission speed is relatively slow. In the case of using the EEPROM, deleting existing data and recording new data, all data recorded in the next order of the deleted area is rearranged in order, and new data is recorded. The control will not be able to do anything else until the same data rearrangement is completed.

Hereinafter, a management method for storing and sorting data of a phone memory according to the related art will be described with reference to the accompanying drawings.

1 is a structural diagram of a telephone memory for storing data according to the prior art.

Referring to FIG. 1, the structure of a memory for storing data in a telephone is a memory consisting of an EEPROM, a data area 10 for storing a telephone number or simple memo data;

It consists of an address area 20 for recording the address of the data stored in each data area 10.

Hereinafter, a management method for storing and sorting data of the telephone memory according to the related art having the above configuration will be described in detail with reference to the accompanying drawings.

In general, the telephone stores simple memo data such as a unique number and a corresponding name of a called party in the data area 10 of the EEPROM and reads the data stored in each data area 10 for the convenience of the user. By reading the corresponding address in the address area 20 by the control unit of the telephone not shown in the figure, it is possible to read the necessary data.

In the conventional phone memory management method as described above, the data to be stored are sequentially stored according to the order of the address area 20. For example, if the data of the order number 5 stored in the EEPROM is unnecessary and deleted, By the control unit, the data recorded in the data area 10 from the current number 6 to the number 99, which is the last number, are moved to the previous number one by one. That is, the data of the sixth address area 20 is transferred to the five address areas 20 and recorded, and this process is repeated, so that the corresponding data of the last 99 address areas 20 is the 98 address area 20. Is written to the data area 10.

Then, the data to be newly recorded is recorded in the corresponding data area 10 of the address area 20 allocated to the last memory area 99. If none of the data already recorded in the data area 10 is deleted, , The data of the first address area 10 is deleted, the data of the address area 10 is moved to the address area 10, and the same process is repeated, address 99 By moving the data of the area 10 to the address area 20, the data area 10 of the address area 20 becomes empty, and the new data becomes the data area of the address area 20. 10) is recorded.

Algorithm by the telephone memory management method of the prior art as described above, since the data stored in the address and the address of the address area 20 is identical, there is an advantage that can use a very simple structure, but in the middle one When the data is deleted, it is moved and sorted in order, so that there is a problem that it takes a long time until the above sorting is completed.

Also, while the above alignment is in progress, the controller of the telephone controls and monitors the operation. There was a problem difficult to do other work.

The present invention provides a first address area for directly managing a data area of a telephone memory, a second address area for indirectly managing a data area by managing the first address area, and a third address for managing a deleted data area. It is an object of the present invention to provide a data management apparatus and method for quickly sorting and storing data even in a slow EEPROM by dividing the data into areas and managing only the second and third address areas.

In order to achieve the above object, the present invention provides a memory for storing data of a telephone, comprising: a data area for storing a unique number of a frequently used callee and simple data for identifying or displaying the unique number; A first address area for storing an address of the data area; A second address area storing a management address of the first address area; And a third address area for storing the deleted area of the first address area.

The method may further include determining whether new data to be stored in the data storage memory is input; A second process of determining whether a value of a deletion counter is set when data to be stored is input; A third step of identifying a third address area of the memory and reading a direct address of a deletion address having a high priority according to whether the deletion counter value is set; A fourth step of decreasing a value of a delete counter by reading a corresponding direct address in the step; A fifth step of checking a second address area storage order of a memory and reading a direct address of the corresponding storage order when the value of the deletion counter is not set in the second step; After the inputted data is recorded in the corresponding data area of the direct address, a sixth process of proceeding to the end process is featured.

Hereinafter, a novel data fast storage device and a method thereof for a telephone memory according to the present invention will be described in detail with reference to the accompanying drawings.

Attached to explain the present invention, FIG. 2 is a structural diagram of a telephone memory for storing data according to the present invention, and FIG. 3 is a flow chart of a novel method for quickly storing data according to the present invention.

Referring to the accompanying drawings, the EEPROM memory 50 for data storage of a telephone, which is used in the present invention, in which a unique number of frequently used callees and simple data for identifying or displaying the unique number are stored. A data area 10 in which such data is stored;

A first address area 20 for storing a direct address of the data area 10;

A second address area 30 for managing the data area 10 as an indirect address by managing the first address area 20;

The third address area 40 manages a direct address of the data area 10 deleted by the user.

The method for quickly storing new data using the EEPROM memory of the phone as described above may include a first step (S10) of determining whether new data to be stored in the memory 50 is input;

As a result of the determination in the first step (S10), if new data to be stored is input, the second step (S20) of determining whether or not the value of the deletion counter to record the value corresponding to the amount of unnecessary and deleted is set; ,

In the second process (S20), when the value of the deletion counter is set, the third address area 40 of the memory 50 is checked, and the direct address (Priority address) of the deletion address with high priority (Priority) Direct address) (3) (S30),

A fourth step (S40) of decreasing the value of the deletion counter by one after reading the corresponding direct address in the third step (S30),

As a result of the determination in the second step S20, when there is no deleted data and the value is set to '0' in the deletion counter, the indirect address storage order of the second address area 30 of the memory 50, That is, the first address of the second address area 30 corresponding to the order of storing the input data is read, and the direct address of the first address area 20 is read by the indirect address. 5 courses (S50),

After the data input for storage in the first process S10 is written to the corresponding data area 10 by the direct address, a sixth process S60 is performed.

Hereinafter, a method of quickly storing new data in a phone memory according to the present invention having the above configuration will be described in detail with reference to the accompanying drawings.

When the telephone user inputs a frequently called telephone number or a unique number (ID) and simple data that can identify the unique number (S10), the controller of the telephone is unnecessary and deleted from the already stored data. It is determined whether the value of the erasure counter having a value of '0', which checks whether there is data (S20).

In the second fixed S20, when the deletion counter value of the telephone is '0', the second address area 30 of the memory 50 is searched to confirm the indirect address of the storage order, and the corresponding indirect address is checked. Read the direct address of the first address area 20 by (S50).

The data input in the first process S10 is recorded in the data recording area 10 of the direct address read by the fifth process S50 and the process proceeds to the end process (S60).

In the second step (S20), when the value of the phone delete counter is set to a value of '1' or more, the third address area 40 of the memory 50 is checked, and the first address area from which data is deleted. Read the direct address of 20 (S30).

In the third process S30, when there are a plurality of direct addresses from which data is deleted, the direct address of the deletion address having a high priority is read.

When the direct address is read in the third process (S30), the value set in the delete counter is decreased by '1' (S40), and the process proceeds to the sixth process (S60) described above.

Therefore, when data is stored using the EEPROM memory 50 of the telephone, which has a low data transmission rate or a driving speed, the data of the data area 10 and the first address area 20, as in the prior art, are stored. The control unit which controls all direct addresses to be rearranged solves the problem of not being able to perform other tasks until the alignment is completed, whereby the second address area 30 having a relatively small area occupying the memory 50 is small. By sorting the indirect addresses of), the data in the memory 50 can be sorted in less time.

In addition, by using the deletion address of the third address area 40, the data area 10 for quickly recording new data can be allocated, and when there is no deleted data, the second address area 30 can be assigned. Among the indirect addresses, the order of storing new data is checked, the corresponding direct address is read, and a data area for storing new data is allocated.

The method for quickly storing new data in the telephone EEPROM memory according to the present invention having the above-described configuration produces the same effect as aligning the data areas by aligning the indirect address areas to which the memory areas are allocated less. By quickly allocating the data area that stores the data, the data can be stored quickly and the control time can be reduced by reducing the occupancy time of the controller, thereby improving the reliability of the telephone. There is.
