Abstract
A memory system is included in a host device. The memory system incudes: a volatile memory device that performs self-refresh until the host device turns on duty when detecting that the host device is off duty; a non-volatile memory device; and a processor that controls a read operation or a write operation of the volatile memory device and the nonvolatile memory device. The processor backs up data stored in the volatile memory device to the non-volatile memory device after a first time period elapses from when the host device is off duty. The volatile memory device stops the self-refresh after a second time period elapses from a time point when the data stored in the volatile memory device is backed up to the nonvolatile memory device.
