CONTROLLER, METHOD OF OPERATING THE CONTROLLER, AND MEMORY SYSTEM HAVING THE CONTROLLER

摘要

PURPOSE: A controller, an operating method thereof, and a memory system including the same are provided to improve error correction performance by correcting error bits. CONSTITUTION: A memory controller(30) controls a nonvolatile memory device(20). A command generating unit(31) generates a read command applied to the nonvolatile memory device. A buffer(32) receives the first page data outputted from the nonvolatile memory in response to a read command and the second page data including error position information corresponding to the first page data. A buffer combines a part of original data with the first page data based on error position information.
