Abstract
In examples, a method of controlling a memory system comprises obtaining a first soft-bit data corresponding to a hard-bit data read from a memory and a first lookup table, where the first lookup table comprises a first log-likelihood ratio determined based on a first reference read voltage of the memory. The method comprises performing a first soft decoding operation according to the first log-likelihood ratio and the first soft-bit data. The method comprises performing at least one shift to the first log-likelihood ratio and performing a second soft decoding operation according to a log-likelihood ratio after each shift and the first soft-bit data when the first soft decoding operation is determined to have failed to decode.
