Abstract
A flash memory controller and a flash memory access method are provided. The flash memory controller comprises a decoder, performing a decoding operation based on a base matrix of a quasi-cyclic low-density parity-check code and the channel values read from a flash memory. The decoder comprises a variable node block, a V2C shift block, a check node block, which are serially coupled. The decoder further comprises a status data shift block, which is parallelly coupled with the check node block, circularly shifts the status data of the check node block and feeds back to the check node block. Due to the number of serially coupled blocks is only three, the convergence speed of the iterative decoding process is improved, thereby the flash memory access performance is enhanced.
