Abstract
A data writing method for writing data from a host system into a flash memory chip is provided, and the flash memory chip has a plurality of physical blocks. The method includes receiving a host writing command and write data thereof, and executing the host writing command. The method also includes giving a data program command for writing the write data into one of the physical blocks of the flash memory chip, and giving a command for determining whether data stored in the physical block has any error bit. Accordingly, the method can effectively ensure the correctness of data to be written into the flash memory chip.
