Abstract: A storage device includes a nonvolatile memory device and a controller that accesses the nonvolatile memory device based on a request of an external host device, receives a first clock signal from the external host device, generates a second clock signal through frequency multiplication of the first clock signal, and communicates with the external host device based on the second clock signal. The controller requests the external host device to adjust a multiplication ratio for the frequency multiplication of the first clock signal.

Abstract: A storage device includes at least one nonvolatile memory device and a storage controller. The storage controller controls the at least one nonvolatile memory device based on a request from an external host. The storage controller adaptively adjusts an impedance of a transmission driver based on a change of an operating temperature of the storage device. The transmission driver transmits a transmission signal to the external host through a link. The storage device may increase an eye height of the transmission signal transmitted to the host through the link by decreasing impedance of the transmission driver as the operating temperature increases. Therefore, the storage device according to example embodiments may maintain reliability of the link even though the operating temperature of the storage device increases.

Abstract: An electronic device includes: a power supply to supply a first power and a second power; a first solid state drive (SSD) backplane and a second SSD backplane to receive the first power from the power supply, each of the first solid state drive (SSD) backplane and the second SSD backplane including two or more SSDs; and a baseboard to receive the second power from the power supply, to independently power on and power off the first SSD backplane and the second SSD backplane, and to access the SSDs of an SSD backplane that is in a power-on state from among the first SSD backplane and the second SSD backplane. In response to an increase in temperature of an SSD backplane that is in a power-off state, at least one SSD of the SSD backplane that is in the power-off state may be powered on.

Abstract: A storage device includes a nonvolatile memory device and a storage controller. The storage controller accesses the nonvolatile memory device based on a request of an external host device. The storage controller sends a signal to the external host device, based a throughput of accessing the nonvolatile memory device being within a specific range.

Abstract: A system includes a transmission device and a reception device that are connected through a link. The reception device includes a reception buffer configured to receive and store transaction layer packets and a reception flow controller configured to generate flow control packets by monitoring an occupation state of the reception buffer. The transmission device includes a transmission buffer, a transmission flow controller and a dynamic frequency controller. The transmission buffer stores pending transaction layer packets to be transferred to the reception device. The transmission flow controller controls a flow of transaction layer packets to be transferred to the reception device based on the flow control packets received from the reception device. The dynamic frequency controller controls a frequency of an internal clock signal of the transmission device by monitoring a state of the transmission buffer and a state of the transmission flow controller.
