Montage Technology today announced the launch of its CXL 3.1 Memory eXpander Controller (MXC, Part No. M88MX6852), now in sampling phase with key customers. Compliant with the CXL 3.1 Type 3 specification, the controller supports both CXL.mem and CXL.io protocols, delivering high-bandwidth, low-latency memory expansion and pooling solutions for next-generation data center servers.

Built on a PCIe 6.2 physical layer interface, Montage's CXL 3.1 Memory eXpander Controller achieves data transfer rates of up to 64 GT/s (x8) and offers versatile configurations with multi-rate and multi-width support, including the option to split into two x4 ports. The chip integrates a dual-channel DDR5 memory controller operating at speeds of up to 8000 MT/s, substantially enhancing data exchange efficiency between the host CPU and backend SDRAM or DIMM modules.
