1. A data processing system comprising:
a storage device configured to: transmit, to an exterior, prediction information, for each power mode, that indicates a predicted time for performing a background operation for managing a memory device; and perform the background operation in an idle state of the storage device by switching to a corresponding power mode in response to a power mode control signal that is received in the idle state; and
a control device configured to: determine a power mode of the storage device and an idle time for the idle state during which the background operation is performed based on the prediction information; transmit the power mode control signal to the storage device; and suspend, during the idle time, execution of a command processing request transmitted to the storage device.
