Montage brings CXL 3.2 memory expansion to AI data centres with Samsung, SK Hynix support

Montage’s launch of the CXL 3.2 memory expansion controller marks a pivotal shift in data center memory architecture, pushing toward higher bandwidth and lower latency. This advancement will significantly boost memory pooling efficiency in AI training clusters, compelling upstream vendors of memory chips and modules to rapidly align. From a compliance standpoint, market entry in the U.S. may trigger export restrictions, especially given the reliance on supply chains from China Taiwan/ Taiwan, China and South Korea, posing risks to procurement stability. Competitors such as NVIDIA and AMD are likely to accelerate their own controller development to maintain ecosystem dominance. Over the next 12–24 months, the CXL protocol is expected to become the de facto standard for memory expansion in AI data centers, driving the entire ecosystem toward more integrated and flexible computing platforms, signaling a fundamental reconfiguration of memory subsystems in heterogeneous computing environments.
