Samsung Launches 512GB Memory Expander CXL DRAM

Today, as a manufacturer of advanced memory technology, Samsung announced the development of Samsung's first 512 GB Memory Extender (CXL, Compute Express Link) DRAM, taking an important step towards the commercialization of CXL. CXL will achieve higher memory capacity and lower latency in IT systems< Br/>

Since the launch of Samsung's first CXL DRAM prototype equipped with on-site programmable gate array (FPGA) controllers in May 2021, Samsung has been working closely with data center, enterprise server, and chipset companies to develop better and customizable CXL products. The all-new CXL DRAM adopts a dedicated integrated circuit (ASIC) CXL controller and encapsulates the DDR5 DRAM with a memory capacity of 512GB for the first time. Compared to the previous Samsung CXL product, the memory capacity is four times that of it and the system latency is only one-fifth of it< Br/>

Chelonian Park, Vice President of Global Sales and Marketing for Samsung Electronics Memory and Director of CXL Alliance, said:; As we actively expand the application of CXL DRAM in the next-generation memory architecture, including software defined memory (SDM), CXL DRAM will become a key turning point in the future computing architecture by significantly promoting AI and Big data services. Samsung will continue to collaborate with the industry to develop and standardize CXL memory solutions, while building an increasingly mature ecosystem& Rdquo; Greg Huff, Chief Technology Officer of Lenovo Infrastructure Solutions Group, stated:; As a member of the CXL Alliance, Lenovo is committed to developing this important standard and helping to build an ecosystem around the new CXL connectivity< Br/>

We are pleased to be a part of Samsung's CXL development plan, striving to promote the development and application of CXL product innovation in future Lenovo systems& Rdquo; Christopher Cox, Vice President of Strategic Technology at Montage Technology, stated:; CXL is a key technology that can manage memory expansion and memory pooling in a more innovative way and will play an important role in the next generation server platform. Lanqi is pleased to continue working with Samsung to help the CXL ecosystem grow rapidly& Rdquo< Br/>

In recent years, the development of Metaverse, artificial intelligence and Big data has given birth to explosive data volume. However, traditional DDR designs limit the expansion of memory capacity to tens of terabytes, requiring a new memory interface technology similar to CXL< Br/>

A large memory pool shared between CXL and main memory, which allows servers to expand their memory capacity to tens of terabytes while increasing bandwidth to the order of terabytes per second< Br/>

The 512GB CXL DRAM will be Samsung's first memory device that supports PCIe 5.0 interface, using EDSFF (E3. S) size specifications, making it particularly suitable for the next generation of high-capacity enterprise servers and data centers< Br/>

Later this month, Samsung will release an updated version of its open-source Scalable Memory Development Kit (SMDK). It is a comprehensive software package that allows CXL memory extenders to work seamlessly in heterogeneous memory systems&# 8217& Flash; Without modifying the existing application environment, system developers can incorporate CXL memory into various IT systems running AI, Big data and cloud applications< Br/>

Starting from the third quarter of this year, Samsung plans to provide samples of 512GB CXL DRAM to customers and partners for joint evaluation and testing. And we plan to prepare for the commercialization of the CXL DRAM product with the launch of the next generation server platform. As a member of the CXL Alliance Board of Directors, Samsung is openly collaborating with many global data center, server, and chipset suppliers to provide next-generation interface technology, bringing profound benefits to the IT industry.
