The present invention relates to a method for reducing storage space of a static random access memory (SRAM) of a mobile communication terminal equipped with a NAND type flash memory. More specifically, it is a NAND type that can be accessed in blocks instead of NOR Type Flash Memory, which can be accessed as an operation code as nonvolatile memory. Storage space of a static random access memory (SRAM) in which a built-in application is copied from a NAND flash memory when the mobile terminal is driven in a mobile terminal using a flash memory (NAND Type Flash Memory) It is about how to reduce.

The mobile communication system has been developed through the first generation analog AMPS (Advanced Mobile Phone System), the second generation cellular (Cellular) and personal communication service (PCS), and recently, the third generation high-speed data. International Mobile Telecommunication-2000 (IMT-2000) has been developed. 1X systems and EV-DO systems are called 2.5 generations because they use the same frequency bands (800 MHz, 1.8 GHz) as the second generation of cellular / PCS services and provide some of the IMT-2000 functionality called the third generation.

In the first and second generation schemes, voice communication is mostly performed using a mobile communication terminal, and data communication has been extremely limited. However, with the advent of 2.5 generation and 3 generation systems due to the steady development of mobile communication technology, the mobile terminal has recently become a core tool for performing data communication.

Recently, with the development of internet and multimedia data technology, a content provider (CP) that provides various contents such as multimedia communication, network game, and video game has emerged, and various services provided by the content provider are provided to mobile communication terminals. The number of mobile subscribers to use has increased.

Therefore, using a virtual machine-based platform made in the Java language as a wireless Internet environment, a built-in application that is built when a mobile communication terminal is launched or a content provider is provided on an information server. The provided content is generated as an application running on the platform and transmitted to the mobile communication terminal carried by the mobile subscriber through the mobile communication network, and the downloaded mobile communication terminal executes the application using the provided platform.

The conventional mobile communication terminal uses a quinoa flash memory as a nonvolatile memory for storing application data running on the platform. Flash memory refers to flash EEPROM (Electrically Erasable and Programmable ROM), and is a read-only nonvolatile memory that can be electrically changed. The performance of flash memory is determined by the memory cell structure and operation method. It is divided into NAND type suitable for data storage and Noah type suitable for writing program code.

The memory cell of a quinoa flash memory is composed of one metal oxide semiconductor (MOS) transistor having a two-layer gate structure having a control gate and a floating gate. In particular, the NOA type flash memory used in the mobile communication terminal interfaces with the control unit through an address bus / data bus and a chip select, read, or write signal. It can be used for program storage and execution because of its random access and random access.

However, in such a Noah-type flash memory, data can be written in units of bytes, but data cannot be deleted in units of bytes. For example, data deletion is performed in blocks of 64K bytes. Therefore, when the data is rewritten arbitrarily, complicated memory management is required such as rewriting the entire block including the data or temporarily moving the block to RAM to rewrite the data and then to the flash memory. In addition, quinoa flash memory not only has a relatively low access speed, but also is expensive and limited in integration, which places a large amount of financial and spatial constraints on storing a large amount of user data and applications with various functions.

As a result, the cost burden of recent Noah-type flash memory and the difficulty of accommodating high-capacity data files increase the use of NAND-type flash memory, which is inexpensive to capacity and relatively fast in access speed. It is a trend.

NAND flash memories include memory cells composed of memory transistors connected in series and arranged in a matrix. The memory cell is composed of a two-layer gate MOS transistor of a control gate and a floating gate, like a quinoa flash memory. Such a NAND flash memory can completely match the unit of data writing and the unit of erasing so that small block units can be written and erased, and since memory cells are connected in parallel, random reads can be performed at high speed. It also has the advantage that several times the memory capacity can be obtained compared to Noah-type flash memory without increasing the chip area.

On the other hand, despite these advantages of NAND flash memory, NAND flash memory has a huge disadvantage. This is because RAM usage increases by the size of the application to be executed due to block-by-block access, which is an advantage and disadvantage of NAND flash memory.

1 is a diagram illustrating a state in which a NAND flash memory in which a built-in application is stored in a conventional mobile communication terminal and data copied from the NAND flash memory during initial setting and driving of the mobile communication terminal are occupied in the static random access memory. .

In general, NAND flash memory is logically divided into areas of Basic Operation Code, Operation Software, Service Data, and User Data. It has a memory map that stores software or data.

The basic operation code is a code for initial setting of the mobile communication terminal. The controller of the mobile communication terminal copies and accesses the basic operation code from the NAND flash memory to the first static memory when the mobile terminal is initially set up, and sets the initial setting of the mobile terminal according to the procedure coded in the basic operation code. To perform.

The operating software is software for driving the mobile terminal so that the mobile terminal can perform basic functions after the mobile terminal performs the initial setting. Operating software is logically divided into static applications and embedded applications. A static application is an application produced by a mobile terminal manufacturer to operate basic functions of a mobile terminal, and an embedded application is mobile so that a mobile terminal can perform basic mobile communication services such as voice and data communication using a mobile communication network. It is an application produced by the operator who operates the communication network.

The service data is an application or data transmitted and received by the mobile communication terminal through the mobile communication network to perform various mobile communication services. The user data is data input by the mobile communication terminal user through the user interface of the mobile communication terminal.

When the NAND flash memory is installed in the mobile communication terminal and the application is executed, the NAND flash memory cannot be accessed in units of bytes but is accessed in units of blocks. Therefore, the control unit cannot execute an application directly from the NAND flash memory. Read into static random access memory where possible and execute in static random access memory.

In addition, the operating software consists of a number of static applications and a number of embedded applications. These applications are not stored separately in NAND flash memory, but are stored as a binary as a bundle and copied into a static random access memory. Is copied as a binary.

That is, when power is supplied to the mobile communication terminal, the controller of the mobile communication terminal copies the basic operation code to the first static random access memory and randomly accesses the basic operation code from the first static random access memory to perform the mobile communication terminal. After the initial setting of the mobile communication terminal is completed, the operating software is copied to the second static random access memory as one binary to randomly access the operating software in the second static random access memory to drive the mobile communication terminal.

As described above, the operating software copied from the NAND flash memory to the second static random access memory when the mobile terminal is driven always occupies the second static random access memory while the mobile terminal is powered on. As a result, the memory storage space of the operating software cannot be used when executing other applications after the mobile communication terminal is run.

Therefore, the storage space of the second static random access memory should be large in proportion to the size of the operating software stored in the NAND flash memory, and the size of the operating software is largely determined by the size of the embedded application, and consequently Storage space was bound to depend on the size of the embedded application.

On the other hand, embedded applications become more and more NAND-type flash memory storage space, depending on the storage space size of the embedded application as the mobile subscribers crave a good mobile communication service, the NAND-type The storage space for static random access memory, which copies embedded applications from flash memory, has also grown.

As described above, in recent years, in accordance with the high demands of mobile subscribers, the size of embedded applications running on mobile terminals is gradually increasing in size, resulting in increased storage space of static random access memory, thereby increasing the price of mobile terminals. This causes the subscriber to inhibit the use of the mobile communication service using the mobile communication terminal and the mobile communication terminal.

In order to solve this problem, the present invention provides a read / write area and a read only area in order to reduce the storage space of the static random access memory of the mobile communication terminal using the NAND flash memory. This provides a built-in application.

In addition, a mobile terminal manufacturer stores the embedded application in a NAND flash memory divided into a read / write storage area and a read-only storage area when the mobile terminal manufacturer manufactures a boot loader for driving the embedded application. By modifying the read-only storage area from the NAND flash memory when the mobile terminal executes the application, the method provides a method of reducing the storage space of the random access memory by not reading the static random access memory.

In addition, a mobile communication terminal which saves the static random memory storage space by dividing the built-in application manufactured by dividing the read / write area and the read-only area into the read / write storage area and the read-only storage area in the NAND flash memory. To provide.

About The people.

2 is a view for explaining an embedded application according to a preferred embodiment of the present invention.

As shown in FIG. 2, the conventional embedded application 210 is simply divided into an application format (AF) and a library format (LF: Library Format). That is, for example, the navigation application includes three application formats and four library formats: navigation.MAF1, navigation.MAF2, navigation.MAF3, navigation.MLF1, navigation.MLF2, navigation.MLF3, navigation.MLF4.

The embedded application 220 according to the preferred embodiment of the present invention reads an application format and / or a library format in which both read and write operations should be performed among the application formats and / or library formats constituting the embedded application. And an area that can only read an application format and / or a library format in which a property is designated as a writeable area (R / W area: Read / Write area, hereinafter referred to as 'R / W area'), and only the remaining reading is performed (R / O area: The property is designated as a Read Only area, hereinafter referred to as an 'R / O area'.

For example, as illustrated in FIG. 2, the navigation application includes navigation.MAF1, navigation.MAF2, and navigation.MLF2 as attributes of the R / W area, navigation.MAF3, navigation.MLF1, navigation.MLF3, and navigation. Specify .MLF4 as the R / O area.

In this case, it is possible to use an option provided by a compiler that compiles an application that specifies an attribute in an R / W area and an R / O area in an application format and a library format constituting an embedded application. .

FIG. 3 is a diagram for describing a method of storing an embedded application in which attributes are specified in a NAND flash memory according to an exemplary embodiment of the present invention.

An embedded application (hereinafter, referred to as an attribute designation embedded application) manufactured as described in FIG. 2 is stored in a NAND flash memory of a mobile communication terminal.

First, in the case of basic operation codes, static applications in operating software, service data, and user data, they are stored and addressed in a conventional manner, but in the case of storing an embedded application having specified attributes in a NAND flash memory, the NAND flash memory is stored. Logically divided into R / W storage area and R / O storage area, and separates the R / W area and R / O area of the embedded application with the specified attributes and stores them in each storage area of flash memory corresponding to each area, Each storage area is given an address separately.

For example, navigation.MAF1, navigation.MAF2, and navigation.MLF2 are stored in the R / W storage area of the NAND flash memory, and 0x13000 for navigation.MAF1, 0x16000 for navigation.MAF2, and 0x18000 for navigation.MLF2. Grant. It also stores Navigation.MAF3, Navigation.MLF1, Navigation.MLF3, and Navigation.MLF4 in the R / O storage area, 0x20000 for Navigation.MAF3, 0x23000 for Navigation.MLF1, 0x28000 for Navigation.MLF3, and 0x33000 for Navigation.MLF4. Give an address.

Here, the reason for storing the R / O area of the embedded application in which the attribute is specified is separately stored in the operating software area instead of storing the R / O area of the NAND type flash memory in the service data area or the user data area. This is because the user data area has a risk that data stored and initialized by the mobile terminal user is deleted, but the operating software area has no risk of data deleted by the mobile terminal user.

Meanwhile, among the operating software of the NAND flash memory, the static application includes a modified boot loader. That is, when the embedded application is driven after the initial setting of the mobile terminal is completed, the controller of the mobile terminal copies the R / W storage area of the NAND flash memory to the second static random access memory to drive the mobile terminal. The boot loader of static applications in software is modified.

The reason for modifying the boot loader like this is that an application format and / or a library format whose properties are specified in the R / W area should be read and written continuously when the application is executed. Since it cannot be deleted, it must be copied to the static random access memory and continuously resided when the mobile communication terminal is driven. In addition, application formats and / or library formats that have attributes assigned to the R / O region do not need to be written, so if necessary, copy them to static random access memory, read them, delete them, and then assign the attributes to another R / O region. This is done by copying and reading the format and / or library format and then deleting it.

4 is a view for explaining a state in which an embedded application of a NAND flash memory is copied to a static random access memory and occupied and resides after driving of a mobile communication terminal.

In the first static random access memory of the mobile communication terminal, basic code data for initial setting of the mobile communication terminal is copied and resides. The controller of the mobile communication terminal randomly accesses the basic operation code copied to the first static random access memory to execute the basic operation code at the initial setting of the mobile communication terminal.

In the second static random access memory of the mobile terminal, after the initial setting of the mobile terminal is completed, operating software, which is software for driving the mobile terminal, is copied and resides. The control unit of the mobile communication terminal randomly accesses the operating software copied to the second static random access memory to execute the operating software.

Among the operating software copied to the second static random access memory, the static application includes a modified boot loader as described with reference to FIG. 3, and after driving of the mobile terminal, the controller of the mobile terminal is configured to have an embedded application according to the modified boot loader procedure. Run

In the case of the embedded application among the operating software copied to the second static random access memory, the R / W storage area of the NAND flash memory is copied to the second static random access memory as it is, and the R / O storage area of the NAND flash memory is It is not copied to the second static random access memory. Therefore, the static random access memory storage space of the size corresponding to the non-copying R / O storage area is saved.

For example, only Navigation.MAF1, Navigation.MAF2 and Navigation.MLF2 stored in the R / W storage area of the NAND flash memory as shown in FIG. 4 are copied to the second static random access memory, and Navigation.MAF3, Navigation. .MLF1, navigation.MLF3 and navigation.MLF4 are not copied to the second static random access memory. Therefore, the storage space of the static random access memory by the size of Navigation.MAF3, Navigation.MLF1, Navigation.MLF3, and Navigation.MLF4 is saved.

5 is a view for explaining the occupancy state of the embedded application resident in the static random access memory after the mobile communication terminal is driven.

In the embedded application 510 occupied in the second static random access memory according to the conventional method when the mobile communication terminal is driven, each application is not distinguished and all application formats and library formats constituting each application are second static random access. Occupying memory

On the other hand, in the case of the embedded application 520 which designates the property occupied in the second static random access memory according to the preferred embodiment of the present invention, only the application format and / or library format in which the property is assigned to the R / W area is copied and occupied. The application format and / or library format specified in the R / O area is not copied, thus saving the storage space of the static random access memory by the size of the application format and / or library format specified in the R / O area. .
