Summary:A joint encoding/decoding method for a solid state drive is provided. Firstly, a data-writing process is implemented for encoding a user data by a hard codec and a soft codec respectively, thereby generating a first number of parity bits and a second number of parity bits. Then, the user data, the first number of parity bits and the second number of parity bits are written into a flash memory module. Then, a data-reading process is implemented for decoding the user data by the hard codec according to the first number of parity bits. If the user data is successfully decoded, the user data is outputted. If the user data is unsuccessfully decoded, a step of decoding the user data by the soft codec according to the second number of parity bits is performed.
