Abstract
A data writing method for a flash memory is provided. The data writing method includes following steps. First, a block is selected as a substitute block from a spare area of the flash memory, wherein the substitute block is used for substituting a data block in a data area for writing a new data. Next, the new data is directly written into the substitute block starting from a start page, wherein there is valid data in the data block before the address for writing the new data. Thereby, meaningless data moving can be reduced, system performance can be improved, and overlong waiting time for writing the new data can be prevented.
