Abstract: A data reading method is provided. The method includes: according to a first read command received from a host system, sending a first read command sequence, which is configured to instruct a reading of a plurality of physical units of the rewritable non-volatile memory module to obtain first data; identifying data stored in at least one first physical unit in the physical units as uncorrectable data according to the first data; according to a second command received from the host system, sending a second read command sequence, which is configured to instruct a reading of the physical units of the rewritable non-volatile memory module to obtain second data; generating response data corresponding to the second read command according to the second data and padding data, which is configured to replace the data read from the at least one first physical unit; and transmitting the response data to the host system.
