Abstract
A data writing method for a rewritable non-volatile memory module, and a memory controller and a memory storage apparatus using the same are provided. The method includes partitioning physical blocks of the rewritable non-volatile memory module into a data area and a spare area and configuring logical blocks. The method also includes selecting physical blocks from the spare area as spare physical blocks corresponding to a logical block and using only lower physical pages of the spare physical blocks to store updated data that is to be written into the logical block. The method further includes moving valid data of all logical pages of the logical block into a physical block of the data area, wherein each lower physical page and an upper physical page corresponding thereto in the physical block are programmed together. Accordingly, the method can effectively improve the speed and reliability of writing data.
