Title: DATA ACCESS METHOD, AND FLASH MEMORY APPARATUS
Abstract:
A data access method, and flash memory apparatus. The flash memory apparatus can reduce the length of valid information bits in data to be encoded, and reconstruct the data to be encoded by padding with configured padding information when saving the data. A controller encodes the reconstructed data according to configured BCH coding, and stores the encoded data. In this way, the present invention ensures data reliability even when an ECC coding method having poorer error correction performance is adopted, and improves the service life of a flash memory apparatus.
