Samsung Unveils 512GB CXL Memory Module

Samsung 512GB CXL

Samsung Electronics has introduced its 512-gigabyte (GB) Compute Express Link (CXL) DRAM. This would mark a significant step forward in the commercialization of CXL. It would allow IT systems to have exceptionally large memory capacity with low latency.

Samsung has been working closely with data center, enterprise server, and chipset businesses to build an upgraded, customized CXL device since initially unveiling this CXL DRAM prototype with a field-programmable gate array (FPGA) controller in May 2021.

The new CXL DRAM is the first to carry 512GB of DDR5 DRAM, with four times the memory capacity and one-fifth the system latency of the previous Samsung CXL offering. It is constructed using an application-specific integrated circuit (ASIC) CXL controller.

“CXL DRAM will become a critical turning point for future computing structures by substantially advancing artificial intelligence (AI) and big data services, as we aggressively expand its usage in next-generation memory architectures including software-defined memory (SDM),” said Cheolmin Park, Vice President of Memory Global Sales & Marketing at Samsung Electronics, and Director of the CXL Consortium. “Samsung will continue to collaborate across the industry to develop and standardize CXL memory solutions, while fostering an increasingly solid ecosystem.”

Scalable Memory Development Kit

A server’s memory capacity may be increased to tens of terabytes while its bandwidth is increased to several terabytes per second thanks to the enormous pool of memory shared between CXL and main memory.

Samsung’s 512GB CXL DRAM would be one of the first to support PCIe 5.0 and will be available in an EDSFF (E3.S) form factor, making it ideal for next-generation high-capacity business servers and data centers.

Samsung expects to release an upgraded version of its open-source Scalable Memory Development Kit (SMDK) later this month. The toolkit is a comprehensive software package that enables system developers to embed CXL memory into various IT systems running AI, big data, and cloud applications without having to alter current application settings.

In the third quarter of this year, Samsung will begin sampling its 512GB CXL DRAM with clients and partners for collaborative assessment and testing, with the memory ready for commercialization when next-generation server platforms become available. Samsung is actively engaging with numerous worldwide data center, server, and chipset makers as a member of the CXL Consortium Board of Directors to create next-generation interface technologies that can bring extremely real advantages to the IT sector.
