Abstract
A data writing method for a rewritable non-volatile memory module containing physical blocks is provided. The method includes: configuring virtual block address to map to at least a part of the logical blocks; receiving a write command which instructs to write file data to the first virtual block addresses, and the first virtual block addresses are mapped to first logical blocks of the at least the part of the logical blocks. The method further includes: writing the file data into the physical blocks mapped to a plurality of second logical blocks; determining whether a program failure is occurred during the writing period; and if the program failure is not occurred, the first virtual block addresses are remapped to the second logical block. Accordingly, the method can ensure the update completeness of the file data.
