Method and apparatus for reading / writing data from / to flash memory and user equipment

摘要

The present invention relates to a method and apparatus for reading / writing data from / to flash memory, and user equipment. The method includes receiving a data read instruction, the data read instruction including a size of the data to be read and a physical address of the data to be read in the flash memory, and a buffer for the physical address. And when the physical address is not found in the buffer, dividing the buffer data area from the internal memory according to the size of the data to be read and the actual physical block size of the flash memory, and according to the physical address Reading data to be read from the flash memory and buffering the data to be read in a buffer data area. Thus, the problems of low read and write efficiency of flash memory and short useful life of flash memory can be solved.
