CXL Memory eXpander Controller (MXC)


The Memory eXpander Controller (MXC) is a Type 3 Compute Express Link™ (CXL™) DRAM memory controller. The MXC supports and is compliant with both DDR4 & DDR5 JEDEC standards. It is also compliant with the CXL 2.0 specification and supports PCIe® 5.0 speeds. The MXC provides high-bandwidth and low-latency interconnect between the CPU and the CXL-based devices, allowing them to share memory for higher performance, reduced software stack complexity, and lower data center TCO.

The MXC is designed to be used in Add-in Cards (AIC), Backplanes or EDSFF memory modules to enable significant scaling of memory capacity and bandwidth for data-intensive applications such as high-performance computing (HPC) and artificial intelligence (AI).
