A method of operation of a controller, which controls a non-volatile memory device, and mapping patterns - selection method for selecting a mapping pattern, comprising a polar coded code word data to a nonvolatile memory device

摘要

An operating method of a non-volatile memory device controller has a form of a code word by means of a polar encoding information bits (s110), a reading of a mapping pattern (s120), the generation of a repeated mapping pattern by repeating the mapping pattern (s130) and a mapping of each bit of the code word to a specific bit of data of the nonvolatile memory device on the basis of the repeated mapping patterns (s140) on.
