Samsung Electronics developed a high-capacity 512GB CXL DRAM for the first time in the industry and accelerated the commercialization of next-generation memory.
※ CXL (Compute Express Link): A newly proposed interface to more efficiently utilize the accelerator, memory, and storage device used together with the CPU in a high-performance computing system.

Samsung Electronics developed the world’s first CXL-based DRAM technology in May last year and has been evaluating it with data center, server, and chipset companies. In addition, the application of an ASIC (application-specific semiconductor)-based controller reduces the data delay time by 1/5 compared to existing products.

This product supports PCIe 5.0, and the EDSFF (Enterprise & Data Center Standard Form Factor) form factor applied to large-capacity SSDs is applied to dramatically expand the DRAM capacity of the existing computing system.

Compared to the explosively increasing amount of data such as metaverse, artificial intelligence, and big data in recent years, the existing DDR interface has a limit in the amount of DRAM that can be loaded into the system, so the demand for next-generation memory solutions such as CXL DRAM continues. is becoming

As Samsung Electronics develops high-capacity CXL DRAM this time, the memory capacity per server along with the main DRAM can be expanded to more than tens of terabytes.

Samsung Electronics will additionally release an updated version of the ‘Scalable Memory Development Kit (SMDK)’ as an open source this month, allowing developers to quickly and easily develop programs that utilize CXL DRAM technology in various application environments. plan to do
※ SMDK: A software development tool that helps the existing main memory and CXL memory operate optimally in the next-generation heterogeneous memory system environment. It consists of APIs, libraries, etc.

“CXL DRAM will innovatively improve services such as artificial intelligence and big data, and will be expanded to next-generation memory including software-defined memory in the future,” said Cheol-min Park, managing director of Samsung Electronics’ new business planning team. Samsung Electronics will actively promote technology standardization with customers and partners so that the CXL memory ecosystem can rapidly expand, and expand CXL memory solutions to lead the next-generation memory market.”

“As a member of the CXL Consortium, Lenovo is contributing to the creation of a CXL-centric ecosystem along with the development of technical standards,” said Greg Huff, CTO, Lenovo Infrastructure Solutions Group. We will work with Samsung Electronics to expand the application of innovative CXL products to Lenovo systems.”

“CXL is a key technology for optimizing memory expansion and sharing and will play an important role in next-generation server platforms,” said Christopher Cox, vice president of strategic technology, Montage Technology. We will work together so that the CXL memory ecosystem can be rapidly expanded.”

Samsung Electronics is expanding cooperation with major global data center, server, and chipset companies to develop next-generation interface technology by participating in the CXL Consortium Board of Directors

Samsung Electronics plans to continuously develop next-generation memory interface products of terabyte or higher and commercialize them in a timely manner in line with the computing market that requires large-capacity memory.
