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: A memory expander includes a memory device having a first memory region corresponding to a first host and a second memory region corresponding to a second host. A controller communicates with the first host and the second host through a compute express link (CXL) interface. The controller receives a first CXL communication packet from the first host and performs a target data transfer operation of transferring target data stored in the first memory region to the second memory region, in response to the first CXL communication packet.

Abstract: A memory expander includes a memory device that stores a plurality of task data. A controller controls the memory device. The controller receives metadata and a management request from an external central processing unit (CPU) through a compute express link (CXL) interface and operates in a management mode in response to the management request. In the management mode, the controller receives a read request and a first address from an accelerator through the CXL interface and transmits one of the plurality of task data to the accelerator based on the metadata in response to the read request.

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 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.

Abstract: An operating method of a memory device which communicates with a first storage device and a second storage device through an interface circuit is provided. The method includes receiving, from a host device, a first request including a command and a first logical block address; obtaining, based on the first logical block address, a first physical block address with reference to first map data dedicated for the first storage device; and sending, to the first storage device through the interface circuit, a second request including the first physical block address and the command.
