May 12, 2018 -- Samsung today announced the development of the first 128GB of CXL 2.0 support, marking another milestone after the release of the CXL 1.1 memory in May 2022.

The CXL 2.0 memory supports PCIe 5.0 ports.With bandwidth up to 35GB/s and capacity up to 128GB, Samsung plans to officially mass-produce CXL 2.0 memory later this year.

This memory supports Intel Xeon processors, although it does not say which generation, but Intel's fourth generation expandable Sapphire Rapids support CXL 1.1, so it is likely to be compatible with the next generation Xeon Emerald Rapids in the second half of the year. It is an enhanced version of Sapphire Rapids.

It's worth noting that Samsung's CXL 2.0 memory is powered by Chinese company Montage's main control chip. "Montage is excited to mass-produce the first CXL 2.0 controllers, and we look forward to continuing to work with Samsung to advance CXL technology and expand its ecosystem," Montage said in the press release.

Montage introduced the new CXL MCX last year,Supports the JEDEC DDR4 and DDR5 standards, meets the CXL 2.0 specifications, and supports PCIe 5.0.

"As a board member of the CXL Alliance, Samsung Electronics has been at the forefront of CXL technology," "This breakthrough reinforces our determination to further expand the CXL ecosystem by partnering with data centers, enterprise-class server and chip companies around the world," said Jangseok Choi, vice president of New Business Planning at Samsung Electronics.

In September 2019, Alibaba, Cisco, Dell EMC, Facebook, Google, HPE, Huawei, Intel, Microsoft (in alphabetical order) jointly announced the establishment of CXL (Compute Express Link Consortium). And announced new board members.

In March 2019, Intel announced the development of CXL open interconnection technology, which serves the next generation of high-performance computing and data centers. The underlying layer is based on PCIe, which can eliminate the transmission bottleneck of computation-based workloads between cpus and devices, cpus and storage, and significantly improve performance.
