Embodiments of the present invention provide a memory access method, device, and system, which can allocate, to a node in a system, a memory resource on which an exclusive access operation can be performed, reduce maintenance overheads of the system, and implement flexible scheduling of memory resources. The device includes a cloud control device on the side of a requesting node and a cloud control device on the side of a contributing node. The cloud control device on the side of the requesting node generates a request packet for accessing to-be-accessed data stored in a memory resource provided by the contributing node to the requesting node for use, receives a response packet, and provides a response message to the requesting node. The cloud control device on the side of the contributing node receives the request packet, provides a request message to the contributing node, generates the response packet for the contributing node, and sends the response packet to the requesting node. |
