Abstract: A memory device is provided. The memory device includes: a buffer memory; a nonvolatile backup memory; and a memory controller configured to: store map data corresponding to an external storage device in the buffer memory; provide, in response to a request from the external storage device, an address pair corresponding to the request, from among address pairs of the map data, to the external storage device; and back up, in response to a sudden power-off event, the map data to the nonvolatile backup memory.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. In addition, the present disclosure relates to a TCP-based transmission control method and apparatus which can reduce a delay time while improving a transmission rate in a communication system. A method for TCP-based transmission control in a communication system according to an embodiment of the present disclosure comprises the steps of: determining a maximum target transmission rate for TCP control using maximum congestion windows (CWNDs) estimated at predetermined times; determining a minimum target round trip time (RTT) for the TCP control using minimum RTTs estimated at the predetermined times; and updating at least one of a congestion window (CWND) and a receive window (RWND) in an RTT time slot, using the maximum target transmission rate and the minimum target RTT.

Abstract: A computing system includes a first storage device, a second storage device, a memory device, and a compute express link (CXL) switch. The memory device stores first map data of the first storage device and second map data of the second storage device. The CXL switch is connected with the first storage device, the second storage device, and an external host through a first interface, and arbitrates communications between the first storage device, the second storage device, and the external host. The first storage device is connected with the memory device through a second interface. The second storage device is connected with the memory device through a third interface. The first interface, the second interface, and the third interface are physically separated from each other.

Abstract: A storage device includes a nonvolatile memory device that stores user data, and a storage controller that controls the nonvolatile memory device under control of a host device. The storage controller includes a storage interface circuit that communicates with the host device through a compute express link (CXL) interface, a NAND interface circuit that communicates with the nonvolatile memory device, and a processor that loads map data from an external memory device through the storage interface circuit and controls the nonvolatile memory device through the NAND interface circuit based on the map data.

Abstract: A method of operating storage devices, a memory device, a host device, and a switch, is provided. The method includes: receiving, by the memory device, a first request corresponding to target user data from the host device; generating, by the memory device, first input/output (I/O) stream information based on telemetry information corresponding to the storage devices and map data in a buffer memory of the memory device based on the first request, wherein the first I/O stream information indicates a data path between a first storage device of the storage devices and the host device; providing, by the memory device, a first redirection request including the first request and the first I/O stream information to the host device or the first storage device through the switch; and processing the target user data according to the first I/O stream information in the first redirection request.
