Abstract: An electronic device may include an embedded storage device connected to directly communicate with an extended storage device, and an application processor connected to directly communicate with the embedded storage device and connected to the extended storage device through the embedded storage device. The embedded storage device includes a monitoring device that monitors commands received from the application processor. The monitoring device generates a command state signal representing a state of the embedded storage device and the extended storage device based on a result of monitoring the commands. The embedded storage device operates so that a power supply is controlled in a part or all of the embedded storage device according to the command state signal.

Abstract: An electronic device includes an embedded storage device and an application processor. The embedded storage device is connected to directly communicate with a removable storage device which processes a packet having a first characteristic. The embedded storage device processes a packet having a second characteristic. The application processor is connected to directly communicate with the embedded storage device, but not directly connected to the removable storage device. The application processor processes a packet having a third characteristic. The embedded storage device compensates at least one of the first characteristic or the second characteristic, such that at least one of a first packet of the first characteristic received from the removable storage device or a second packet of the second characteristic in the embedded storage device is provided to the application processor according to the third characteristic.

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.
