Abstract
Read data associated with Flash storage is received. One of a plurality of LLR mapping tables is selected and a set of one or more LLR values is generated using the read data and the selected LLR mapping table, where each LLR value in the set of LLR values has a same finite precision as a finite-precision low-density parity-check (LDPC) decoder. Error-corrected read data is generated using the set of LLR values, where the finite-precision LDPC decoder has the same finite precision as the set of LLR values. The error-corrected read data is output.
