A flash memory configuration and access method having a particular conversion method that uses the page or the sector in each flash memory block instead of the block that is commonly used as the base of the data conversion storage to store data. When data is written into the physical flash block of the flash memory, the original logic sector information can be preserved. The data is written into the same block of the flash memory in a manner according to the sequence as it is received instead of the sequence of the logic sector. Therefore, the block position does not move to refresh the block content until the physical block is full. Consequently, the number of times to move the physical block of the flash memory can be reduced to increase the lifetime of the flash memory. Moreover, since the number of times to erase is reduced, so that the writing speed can speed up to improve the operation efficiency.
