Abstract
A data storage method for a flash memory storage device is provided. The method includes disposing a pattern identification unit in the flash memory storage device and disposing a pattern analysis unit in a host connected to the flash memory storage device. The method further includes analyzing a usage pattern of each flash memory storage address in the flash memory storage device by using the pattern analysis unit, receiving information from the pattern analysis unit through the pattern identification unit to identify the usage pattern of each flash memory storage address, and storing data into each flash memory storage address through a corresponding process according to the usage pattern of the flash memory storage address. Thereby, data can be stored according to the usage pattern of each flash memory storage address, and accordingly the speed of storing data into the flash memory storage device can be effectively increased.
