Abstract: A storage device includes a controller that is configured to perform two-way communication with a host. The controller generates a plurality of requests including first requests and second requests associated with the host. The controller orders the plurality of requests such that the plurality of requests include at least one first request and at least two consecutive second requests.

Abstract: A storage device includes a memory controller to receive a first signal from an external device through a first channel, obtain data from a memory based on the first signal, and output the data to the external device through a second channel. The data is output through the second channel in a case where a time interval between a time when the first signal is received and a time when the data are obtained is greater than a first reference interval.

Abstract: A method of controlling a link state of a communication port of a storage device according to the present inventive concepts includes setting the link state of the communication port to a link active state that can exchange data with a host, determining a holding time of a first standby state among link states of the communication port, changing the link state of the communication port to the first standby state, monitoring whether an exit event occurs during the holding time from the time when a transition to the first standby state occurs, and in response to an exit event not occurring during the holding time, changing the link state of the communication port to a second standby state. A recovery time from the first standby state to the link active state is shorter than a recovery time from the second standby state to the link active state.
