Problems solved by technology

However, the above-mentioned mechanism of dividing the swap space (SWAPspace) in the hard disk in order to prevent the computer system from crashing will not cause any problems (for example, due to too many access times) damage to the hard disk), but for a computer system equipped with a solid-state hard disk (SSD) with a short lifespan, under such a mechanism, the user will save the solid-state hard disk (SSD) after each boot and enter the operating system. Get, as time passes, will certainly more quicken the shortening of the service life of solid-state hard drive (SSD) in computer system, therefore, how to improve at this problem, for the main purpose of developing the present invention

Embodiment Construction

[0033] See figure 1 , which is a functional block diagram of a computer system with storage control function developed by the present invention to improve the lack of known technical means. We can clearly find out from the figure that this computer system 1 mainly uses the central processing unit (CPU) 10 as the system backbone, and the signal connection of the central processing unit 10 is connected between the north bridge chip (North Bridge Chip) 111 and the south bridge chip (South BridgeChip). ) 112 composed of a bridge chip set (Chipset) 11, wherein the north bridge chip 111 communicates with the central processing unit 10 with a front side bus (Front Side Bus, FSB) 1001; communicates with the main memory (Main Memory) 12 with a memory bus 1002 And use the AGP bus 1003 to communicate with the graphics acceleration port interface (Accelerated Graphics Port, AGP) 13, and the South Bridge chip (South Bridge Chip) 112 is connected with the peripheral component connection int...

Abstract

The invention relates to a computer system and a storage control method. The computer system comprises a storage device and a main memory. The method comprises the following steps: the computer system is started; whether the storage device is a semiconductor nonvolatile one is detected; when the storage device is a semiconductor nonvolatile one, the formation of a virtual memory space in the storage device is stopped; an application program is executed; adaptation to the application program is carried out and a memory space is divided from the main memory; a temporary file or a log file generated when the application program is carried out is stored in the memory space divided from the main memory. The computer system and the method of the invention can prolong the service life of the storage device in the computer system.

Description

technical field [0001] The invention relates to a computer system and its storage control method, in particular to a computer system with a semiconductor non-volatile storage device and its storage control method. Background technique [0002] NAND flash memory (NAND flash) is a kind of non-volatile memory (non-volatile), mainly used to store boot programs (such as basic input and output system program code) or system data, because NAND flash memory can be easily rewritten Therefore, NAND flash memory gradually replaces flash memory such as ROM, PROM, EPROM, EEPROM, etc. that cannot be rewritten or the steps of rewriting are quite cumbersome. NAND flash memory has the advantages of fast writing, fast erasing, and high density, so NAND flash memory is mostly used in mobile devices, such as mobile phones, MP3 players, MP4 players, digital multimedia players, etc. NAND flash memory can be used as a The medium for storing multimedia files in the device focuses on the low cost, ...
