Abstract
A non-volatile memory controller for a solid state drive includes a soft-decision LDPC decoder. The soft-decision LDPC decoder includes a probability generation module. A processor reads collected statistics collated from decoded frames and tunes the performance of the soft-decision LDPC decoder performance. Additional parameters may also be taken into account, such as the scramble seed and the type of non-volatile memory. An asymmetry in errors may also be detected and provided to a hard-decision LDPC decoder to adjust its performance.
