Abstract: Disclosed is a storage device which includes an interface circuit that exchanges data with a host device, and a power management unit that supplies a power to the interface circuit. The interface circuit includes a first input terminal receiving a first signal from the host device, a second input terminal receiving a second signal complementary to the first signal from the host device, a receive module processing the first signal and the second signal, a squelch circuit detecting levels of the first signal and the second signal, and a reference clock detector detecting whether a reference clock for operating the storage device is received. The power management unit selectively supplies a power to the squelch circuit based on a result of the detection by the reference clock detector.

Abstract: A device includes a first input/output (I/O) port for communication with an external processor, a second I/O port for communication with a second device, and an interface adaptor supporting communication through the first and second I/O ports via a protocol having a plurality of layers, including an application layer, a physical layer, and a physical adaptor layer. The application layer processes information according to an application layer format and the physical adaptor layer processes information according to a physical adaptor layer format. The device receives from the external processor through the first I/O port a request in the application layer format that one or more communication conditions be set for a physical layer of the second device, converts the request from the application layer format to the physical adaptor layer format, and sends the converted request in the physical adaptor layer format to the second device through the second I/O port.
