Abstract
An operating method of a nonvolatile memory device controller includes generating a code word through polar encoding of information bits, reading a mapping pattern, generating a repeated mapping pattern through iteration of the mapping pattern, and mapping each bit of the code word onto a specific bit of multi-bit data of the nonvolatile memory device, based upon the repeated mapping pattern.
