Abstract
A data processing system includes a host device including a first volatile memory device, and a data storage device including a second volatile memory device and a nonvolatile memory device, and suitable for storing data to be accessed by the host device. The data storage device uploads data stored in the second volatile memory device to the first volatile memory device before the data storage device in a normal mode enters a power-save mode.
