Abstract
A flash memory controller, to be coupled between a host device and a flash memory module, includes an error correction code (ECC) circuit. The ECC circuit performs a wordline-dimensional ECC operation upon specific data, sent from the host device to form a super block stored within the flash memory module, to generate wordline-dimensional parity data and performs a finger-dimensional ECC operation upon the specific data generate finger-dimensional parity data. The ECC circuit corrects an error of the superblock by using the wordline-dimensional parity data and the finger-dimensional parity data so as to obtain correct data content of the specific data.
