Abstract: A network storage device connected with a network fabric includes a network storage controller that performs interfacing with the network fabric and translates and processes a command provided through the network fabric, and a nonvolatile memory cluster that exchanges data with the network storage controller under control of the network storage controller. The nonvolatile memory cluster includes a first nonvolatile memory array connected with the network storage controller through a first channel, a nonvolatile memory switch connected with the network storage controller through a second channel, and a second nonvolatile memory array communicating with the network storage controller under control of the nonvolatile memory switch.

Abstract: A transmitter includes: a pulse amplitude modulation encoder that encodes serial data to multi-bit transmission data of a first data group and a second data group; a first driver that converts first multi-bit transmission data of the first data group to a first differential signal having a first voltage swing width; a second driver that converts second multi-bit transmission data of the second data group to a second differential signal having a second voltage swing width narrower than the first voltage swing width; a first voltage regulator that provides to the second driver a first low swing voltage for generating the second differential signal; a second voltage regulator that provides to the second driver a second low swing voltage less than the first low swing voltage; and a constant current load switch that provides a current path between the first and second voltage regulators depending on deactivation of the second driver.

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.
