    摘要: A data writing method for flash memory and an error correction encoding/decoding method thereof are disclosed. In an embodiment of the data writing method, a 6-bit ECC scheme using a Reed-Solomon code derived from a Galois Field GF (29) is used to encode a data for generating a redundant which requires smaller storing space. In an embodiment of the error correction encoding/decoding method, an erase checking value corresponding to the status where all the bytes of data area and parameter storing area are “0xff” is provided to improve the security of stored data.
