Abstract
A memory system, a memory controller and a method for operating a memory system are disclosed. Specifically, by performing soft-decision decoding for data read from some of the plurality of memory cells based on a first optimum read voltage of one or more optimum read voltages, based on reliability values of one or more first threshold voltage sections, and one or more second threshold voltage sections and also based on the first and second threshold voltage sections, it is possible to provide a memory system, a memory controller and a method for operating a memory system, capable of increasing an error correction effect by soft-decision decoding even in the case where threshold voltage distributions of memory cells in which data is stored are degraded.
