Abstract
A flash memory controller used to access a flash memory includes a read-only memory, a processor, and an error correction code unit. The read-only memory is used to store a code. The processor executes the code to control access to the flash memory. The error correction code unit includes a control module and a decoder. The control module respectively calculates a first correlation between innate bad-column information which records the location of innate bad columns that become damaged after the read-only memory being manufactured and a plurality of trapping sets of a plurality of preset LDPC (low-density parity check) codes and uses the preset LDPC code which has the lowest first correlation as a selected LDPC code. The decoder decodes read information obtained from the flash memory according to the selected LDPC code.
