Abstract
A data writing method for a flash memory is provided. The data writing method includes: dividing a new data into at lease one sub-data by the size of a writing unit; selecting one of a plurality of spare blocks from the flash memory as a substitute block for substituting a data block, wherein the new data is to be written into the data block; sequentially writing the sub-data having the size of the writing unit into the substitute block in the writing unit; and storing the sub-data not having the size of the writing unit into a temporary area. The writing efficiency of the flash memory can be improved by temporarily storing the sub-data not having the size of the writing unit into the temporary area and then writing the sub-data not having the size of the writing unit with subsequent data into the substitute block.
