  • Data storage method for flash memory, and flash memory controller and flash memory storage system using the same
    Patent number: 8898370
    Abstract: A data storage method for storing data into a flash memory chip is provided. The flash memory chip has a plurality of physical addresses, and these physical addresses include a plurality of fast physical addresses and a plurality of slow physical addresses. In the data storage method, the usage rate of the physical addresses is monitored. When the usage rate is not larger than a usage rate threshold value, only the fast physical addresses are used for storing the data into the flash memory chip. When the usage rate is larger than the usage rate threshold value, the fast physical addresses and the slow physical addresses are used for storing the data into the flash memory chip. Thereby, the speed of storing data into the flash memory chip is effectively increased.
