Abstract
Systems, devices, and methods are presented that allow a data channel to adaptively vary a change in a reference voltage used to read data from a solid state memory. The change in the reference voltage may be determined based on a measured error statistic of the solid state memory. A hard decision low density parity check (HLDPC) decoder may be utilized in conjunction with a soft decision low density parity check (SLDPC).
