MemCon: XConn Releases Early Production Silicon Samples of Apollo CXL 2.0 Switch

Hybrid CXL 2.0 and PCIe Gen 5 interconnect solution

XConn Technologies announced the early production samples for its Apollo CXL 2.0 switch.


XConn Apollo was the central component of a real-world use case demonstration of a CXL Memory Pool, with Samsung Semiconductor during MemCon 2024, March 26-27, in Mountain View, CA..

The XConn Apollo switch is an industry’s 1st and only hybrid CXL 2.0 and PCIe Gen 5 interconnect solution. On a single 256-lane SoC, it offers the industry’s lowest port-to-port latency and lowest power consumption per port in a single chip at a low TCO. Designed for use with Samsung DRAM Memory Expander supporting CXL, it removes the traditional memory barriers to change memory architecture.

Together with the CXL community, XConn is revolutionizing the memory landscape to unlock technology innovation and application performance, for generative AI as well as general cloud computing,” said Gerry Fan, CEO, XConn. “Today’s release of production silicon samples of our Apollo CXL 2.0 switch marks a new milestone in our next-generation interconnect journey. We are now empowering the realization of CXL’s promise and showing its practical use with a CXL memory pool.” 

At MemCon 2024, Samsung is excited to showcase the real-world value of CXL memory technology in action,” said Dr. Sungwook Ryu, head, memory solutions lab, Samsung Semiconductor. “We strongly support the collaborative CXL ecosystem and will continue to work with CXL players to accelerate the adoption of this memory innovation. XConn CXL switch SoC chip is used in Samsung CMM-B (CXL Memory Module – Box).

Available in production samples, the company’s Apollo switch also supports a PCIe Gen 5 only mode for AI-intensive applications and is a key component in Open Accelerator Module (OAM), JBOG and Just-a-Bunch-of-Accelerators (JBOA) environments. It features full support for CXL 2.0, is backwards compatible with CXL 1.1 and supports PCIe Gen 5 in hybrid mode.

The XConn and Samsung demonstration was featured during MemCon 2024, March 26-27, at the Computer History Museum in Mountain View, CA. in the Samsung booth.
