Compute Express Link (CXL) in the explanations
CXL runs on the same physical layer as PCI Express and adds protocols that maintain cache coherence and let the CPU read and write device memory like ordinary memory.
Which describes CXL (Compute Express Link)?CXL memory adds capacity by attaching memory devices to PCI Express slots or similar, and with switches several servers can share pooled capacity.
