Abstract
Disclosed is a memory system. The memory system includes a volatile memory device configured to exchange data with a host through a first channel, a nonvolatile memory device, and a memory controller connected with the volatile memory device through a second channel. The memory controller detects a request of the host or a power state and controls the volatile memory device and the nonvolatile memory device based on the detection result such that data stored in the volatile memory device is backed up in the nonvolatile memory device through the second channel. The volatile memory device includes a first interface for communicating with the host through the first channel and a second interface for communicating with the memory controller through the second channel.
