Samsung Unveils Industry’s First Memory Module With New CXL Interconnect Standard | Business


SEOUL, South Korea – (BUSINESS WIRE) – May 10, 2021 –

Samsung Electronics Co., Ltd., the world leader in advanced memory technology, today unveiled the industry’s first memory module that supports the new Compute Express Link (CXL) interconnect standard. Integrated with Samsung’s Double Data Rate 5 (DDR5) technology, this CXL-based module will allow server systems to dramatically increase memory capacity and bandwidth, thereby accelerating artificial intelligence (AI) workloads and high performance computing (HPC) in data centers.

The rise of AI and big data has fueled the trend towards heterogeneous computing, where multiple processors work in parallel to process huge volumes of data. CXL – an open, industry-supported interconnect based on the PCI Express (PCIe) 5.0 interface – enables high-speed, low-latency communication between the host processor and peripherals such as accelerators, memory buffers and intelligent I / O devices, while increasing memory capacity and bandwidth far beyond what is possible today. Samsung has been working with several data center, server, and chipset manufacturers to develop next-generation interface technology since the creation of the CXL consortium in 2019.

“This is the industry’s first DRAM memory solution running on the CXL interface, which will play a critical role in delivering data-intensive applications including AI and machine learning in data centers. data as well as in cloud environments, ”said Cheolmin Park, vice president. Chairman of the Memory Product Planning Team at Samsung Electronics. “Samsung will continue to raise the bar with innovation in memory interfaces and scaling of capacity to help our customers, and the industry as a whole, better manage real-time workload demands.” larger, more complex, and critical to AI and data centers. of tomorrow. “

Dr. Debendra Das Sharma, Intel Fellow and Director of I / O Technology and Standards at Intel, said: “The data center architecture is evolving rapidly to support the growing demand and workloads for AI and ML, and CXL memory is expected to expand memory usage to a new level. We continue to work with industry companies such as Samsung to develop a robust memory ecosystem around CXL. “

Dan McNamara, senior vice president and general manager, Server Business Unit, AMD, added, “AMD is committed to driving the next generation of performance in cloud and enterprise computing. Memory research is a critical part of unlocking this performance, and we are excited to work with Samsung to provide advanced interconnect technology to our data center customers. “

Unlike conventional DDR memory, which has limited memory channels, Samsung’s CXL compatible DDR5 module can scale memory capacity to the terabyte level, while dramatically reducing system latency caused by caching. Memory.

In addition to CXL hardware innovation, Samsung has incorporated several controller and software technologies such as memory mapping, interface conversion, and error handling, which will allow processors or GPUs to recognize memory based. on CXL and use it as main memory.

Samsung’s new module has been successfully validated on Intel’s next-generation server platforms, ushering in an era of high-bandwidth, low-latency CXL memory using the latest DDR5 standard. Samsung is also working with data center and cloud providers around the world to better meet the need for more memory capacity that will be critical in the management of big data applications, including in-memory database systems. .

As the DDR5-based CXL memory module is released, Samsung intends to become the industry leader in meeting the demand for next-generation high-performance computing technologies that rely on memory capacity and extensive bandwidth.
