Title: Memory system including nonvolatile memory and volatile memory and operating method of same

Abstract: A volatile memory has a volatile additional area for storing an error correction code for a nonvolatile memory. Data stored in the nonvolatile memory are transferred to the volatile memory together with the error correction code without making an error correction. Thus, data transfer time from the nonvolatile memory to the volatile memory can be shortened. As a result, it is possible to shorten the time from beginning of the data transfer from the nonvolatile memory to the volatile memory to a point at which data becomes accessible.
