Abstract: A computing system includes a host, a memory, and a storage device. The memory includes a volatile memory and a memory controller. The storage device is connected with the host through a first interface and includes a nonvolatile memory and a storage controller, the storage device communicating with the host through a first port, communicating with the memory through a second port, and managing the memory. The memory is connected with the storage device through a second interface that is physically separated from the first interface. In an initialization operation, the storage controller sends map data that is stored in the nonvolatile memory to the memory through the second interface. In the initialization operation, the memory controller stores the map data in the volatile memory.

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 method of operating a computing system which includes a plurality of storage devices, a memory device, and a switch, is provided. The method includes: providing a first mapping request including first metadata corresponding to first user data to the memory device through the switch, by a first storage device of the plurality of storage devices; identifying a first standard corresponding to the first metadata based on the first mapping request, by the memory device; and generating first map data indicating a relationship between a first physical block address and a first logical block address of the first user data based on the first standard, by the memory device.

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.
