At present, the industry has further developed the so-called solid state disk (Solid State Disk or Solid State Drive, SSD) with NAND flash memory and appropriate control chip, which has higher speed and no noise. The advantages of anti-vibration and power saving can further replace the hard disk currently storing materials with magnetic substances, and then applied to personal computers or notebook computers, but the biggest disadvantage of solid-state hard disk (SSD) compared with traditional hard disks is that The high cost of solid-state hard disk (SSD) φ and the short use of life, especially in terms of service life, is a fatal injury that solid-state hard disk (SSD) has never been popularized. Generally, after the computer system is turned on and the operating system is turned on, the file executed by the computer system is too large, and the capacity of the computer system master memory (MM) cannot cope with the time of the file executed by the computer. In order to prevent this from happening, in addition to the original main memory (MM), the computer system will be on the hard disk at the same time every time the computer system is turned on. A virtual memory space, also known as swap space pe), compensates for the lack of capacity of the original main memory (Ram). In addition, the user performs various kinds of temporary data generated by the operation _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The temporary data such as the log file (logflle) generated by various working procedures is stored in the exchange (4) (·ρ, sfee) in addition to the temporary record (4), in order to prevent the computer system from crashing. Hard disk - ^ cut out the swap space (S change ah e) _, for the hard county that uses magnetic 201005522 material storage information, there will be no side problems (such as hard times caused by too many access times), However, for a computer system equipped with a short solid-state hard disk (SSD), under such a =, the user will access the fixed disk (SSD) every time after entering the secret. Over time, it will inevitably accelerate the shortening of the service life of solid-state disk (SSD) in computer systems. Therefore, how to improve this problem is the most important purpose of the development of this case. , ❼

The computer system includes a storage device and a main memory. The method includes the following steps: starting the computer system; whether the side storage device is a semiconductor non-storage storage a device; when the storage device is a semi-conducting financial storage device, 'stops the storage device to form a virtual memory space; executes an application program; and the target thief relies on execution and divides in the social record - memory space And the execution of the program - the temporary storage of a login machine exists in the memory of the memory device. The other aspect is a computer system comprising: a main memory: The second storage device stores the operating system: and the processing unit 70', which is executed after the computer secret is started, and executes the operating system stored in the storage device, and executes the job. When the detection storage device is - semiconductor non-volatile _ money set, stop the storage set-up memory, if the program is executed (four) and in the main record shop (four) - memory (four), the application will be executed201005522. One of the temporary archives or a log file stored is stored in the memory space partitioned in the main memory. [Embodiment] Please refer to the first figure, which is a block diagram showing the function of the computer system with storage control function developed to improve the technical means. As can be clearly seen from the figure, the computer system i mainly uses a central processing unit (CPU) 10 as a system backbone, and the central processing unit ❹ 10 signal is connected to a north bridge chip 111 and a south bridge chip. (South Bridge Chip) 112 is a bridge chipset (Chipset) 11, wherein the north bridge chip U1 is connected to the central processing unit 1 by a front busbar (FSB) 1001; The body bus bar 1002 is interconnected with a main memory (Main Mem〇fy) 12 and communicates with an AGP bus bar 1003 with an Accelerated Graphics Port 'AGP 13 , and the South Bridge Chip 112 is connected to a peripheral φ component interface (PCI) 14 by a PCI bus bar 1004, and a universal serial bus (USB) interface is also connected to the south bridge chip 112. j 5 and an IDE (Integrated Drive Electronics) interface 16, wherein a storage device 17 is connected to the IDE interface 16. The main technical means of the computer system described in the present invention is that after the computer system 1 is started, the central processing unit 1 starts to execute an operating system stored in the storage device 17 (not shown in the figure). During the execution of the operating system by the central processing unit 10 (for example, the initialization phase of the 201005522 computer system 1 or the type of the operating system i:, two: will start detecting the storage device 17 volatile storage The right storage device 17 is a semiconductor non- or single-stage storage == type: state hard disk (a) 10# with T, hit)), the central processing unit storage device I 17 / through the wealth bridge 4 groups The transmission of 11 stops at this ~ into a virtual memory space of this program, that is, the 2nd camphor system will be in the storage device (hard disk) _ split out too, +: space (SWAP space) this mechanism When the user executes a program such as a web page browser or a word processing program in the computer system 1 of the location, the central processing unit H) issues a command to transmit through the = chip group u. Segment 12 in the body 12, and instead of storing The virtual memory space in the device 17 is used to store the temporary miscellaneous (temp〇rai or login file (i〇gfiie) of these Weixing. Through the above, we can clearly understand that there is Storage control Wei Zhidian, mainly when the computer system is configured as a multi-level storage solid-state hard disk (MLC SSD) or a single-stage storage solid-state hard disk (SLC SSD) semiconductor non-volatile storage device, in the computer After the system is turned on, the mechanism of "forming SWAP swap space in the storage device" will be banned, that is, after the computer system is turned on and the operating system is mentioned in the prior art of the present case, when the computer system is turned on. The file being executed is too large, and the capacity of the main memory (RAM) of the computer system cannot cope with the age of the computer. The entire age of the computer will occur when the machine 9 201005522 occurs, so to prevent this from happening. In addition to the original main memory (RAM), every time the computer system is turned on, the computer system will simultaneously split the virtual memory on the hard disk. The technical means described in this case is The computer system disables this mechanism of the virtual memory space on the storage device to reduce the semiconductor non-storage of solid-state hard disk (MLC SSD) or single-stage storage solid-state hard disk (SLc ssd). The number of times the bumper storage device is accessed, in this way, can effectively extend the service life of the type of storage device in the computer system. In addition, the SWAP exchange space is formed in the storage device. This machine may be caused by (10) The risk of the computer system crashing, the technical means described in this case will be divided into a virtual memory formed in the main memory of the computer system instead of the virtual memory formed on the storage device to store the temporary archive generated when the application is executed. (temporal flle) or login step = scale (four) describes the case of the ride, such as the method of loss of the ^ ^ ^ ^ map, which is the case for the improvement of the conventional technical means of the lack of map = - figure shown in the functional square This two = 17 is a sudden) Computer system 1 detects the storage of the heart is a volatile storage device (if the detection node 1 stops _ ^ ^ ^ conductor non-missing storage device, Qing computer system, ° child And a virtual memory space is formed in the 17th (step S3丨. _(4) face-to-face program and the body 201005522 12 divides a memory space (step S4); the computer system ι will execute the temporary file generated by the application (temp〇) The storage path of the ral or log file is set to be stored in the memory space partitioned by the main memory 12 (step S5); and, in step S2, the computer system detects the storage. The detection result of the device 17 is that the storage device 17 is a magnetic storage device (such as a hard disk), and the computer system i forms a virtual memory space in the storage device 17 (step S6); The generated temp〇ral file or login file (l0g twitched storage path is set to be stored in the virtual memory space of the storage device 17 (step π). According to the above technical description, the computer system described in step S4 splits the memory space in the main memory according to the user's execution of the application program to store and execute the female job temporary miscellaneous (tempGml Tao or login file (log File) 'The technical means is the "RAMDISK technology" used to improve the performance of computer systems. The so-called ^_ muscle technology will virtualize the main memory in the computer system into a disk drive, with the main Memory fast access speed silk storage requires fast access but is not very important data file 'for example · the user executes the temporary directory generated by the web browser after viewing the web page. Therefore, through step 2 and steps 3, the method of performing gamma on the storage device and the result of the non-semiconductor storage device is stopped, and the technical means of forming the virtual memory between the storage devices is stopped, and the application from the dirty sheet technology is matched. Ben: The technical means described can effectively reduce the number of solid-state hard drives (mlcssd) 11 201005522 or single-stage storage solid-state drives without affecting the power (4). The number of times the semiconductor non-volatile storage device of mlcssd is accessed, thereby prolonging the service life of the semiconductor non-volatile storage device in the computer system t. The above technical description 'we can clearly understand the storage control described by the invention of the present invention The method can effectively reduce the number of times the semiconductor non-volatile storage device is accessed in the computer system when the computer system is configured with the semiconductor non-volatile storage device, thereby prolonging the use of the storage device in the computer system. The lifespan, in turn, achieves the most important purpose of the development of the present invention, and the present invention has been modified by those skilled in the art, and is not intended to be protected by the scope of the patent application. 】 This case can be obtained from the following diagrams and explanations, and a deeper understanding of the company's figure.
