摘要： 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.

摘要： 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.

摘要： 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.

摘要： A memory device is provided. The memory device includes: a buffer memory; and a memory controller configured to: obtain map data and meta data for recovering the map data from at least one external storage device; store the map data and the meta data obtained from the at least one external storage device in the buffer memory, the buffer memory being allocated for the at least one external storage device; translate a logical address corresponding to the at least one external storage device into a physical address of the buffer memory; and send the map data and the meta data to the at least one external storage device in response to detecting a sudden power-off event.

摘要： A computing device includes a storage device and a memory. The storage device includes nonvolatile and internal buffer memories, and a storage controller that controls the nonvolatile and internal buffer memories and communicates with a bus. The memory includes a buffer memory and a memory controller that controls the buffer memory and communicates with the bus. The nonvolatile memory stores user data and map data. In an initialization operation, the storage controller sends the map data to the memory through the bus, and the memory controller stores the map data that is transferred from the storage device through the bus, in the buffer memory. After the initialization operation, the memory controller sends partial map data of the map data to the storage device through the bus, and the storage controller stores the partial map data that is transferred from the memory through the bus, in the internal buffer memory.
