Samsung launches the industry’s first memory module incorporating the new CXL interconnect standard

DDR5 DRAM-based memory modules are designed to meet the high-performance needs of data-intensive applications such as AI and HPC

The CXL interface enables the memory capacity to be expanded to terabytes and greatly reduces system latency

Samsung Electronics Co., Ltd., a global leader in advanced storage technology, today released the industry’s first storage module that supports the new Compute Express Link (CXL) interconnect standard. The CXL-based module is integrated with Samsung’s Double Data Rate 5 (DDR5) technology, which will enable server systems to significantly expand memory capacity and bandwidth, thereby accelerating artificial intelligence (AI) and high-performance computing (HPC) workloads in data centers .

The rise of artificial intelligence and big data has promoted the trend of heterogeneous computing. In heterogeneous computing, multiple processors work in parallel to process large amounts of data. CXL is based on the PCI Express (PCIe) 5.0 interface, an open interconnection supported by the industry, which can perform high-speed, low-latency between the host processor and devices (such as accelerators, memory buffers, and smart I/O devices) Communication, while expanding memory capacity and bandwidth far exceeds today’s capabilities. Since the establishment of the CXL Alliance in 2019, Samsung has been cooperating with multiple data center, server and chipset manufacturers to develop next-generation interface technologies.

“This is the industry’s first DRAM-based memory solution running on the CXL interface. It will play a key role in serving data-intensive applications, including AI and machine learning in data centers and cloud environments,” Cheolmin Park Represents the president of Samsung Electronics’ memory product planning team. “Samsung will continue to raise standards through memory interface innovation and capacity expansion to help our customers and the industry as a whole better manage the needs of larger, more complex, real-time workloads that are critical to AI and data centers tomorrow.”

Dr. Debendra Das Sharma, Intel Academician and Director of Intel I/O Technology and Standards, said: “Data center architecture is evolving rapidly to support the growing demand and workload for AI and ML, and CXL memory is expected to expand to a new level of memory. We continue to cooperate with Samsung and other industry companies to develop a strong memory ecosystem around CXL.”

Dan McNamara, senior vice president and general manager of AMD’s server business unit, added: “AMD is committed to promoting the next generation of cloud and enterprise computing performance. Memory research is the key to unlocking this performance, and we are excited about it. Working with Samsung, To provide our data center customers with advanced interconnect technology.”

Unlike traditional DDR-based memory which has limited memory channels, Samsung’s CXL-enabled DDR5 module can expand the memory capacity to terabytes while significantly reducing system latency caused by memory cache.

In addition to CXL hardware innovations, Samsung has also adopted a variety of controller and software technologies, such as memory mapping, interface conversion, and error management, which will enable the CPU or GPU to recognize CXL-based memory and use it as main memory.

Samsung’s new module has been successfully verified on Intel’s next-generation server platform, which marks the beginning of the era of high-bandwidth, low-latency, CXL-based memory using the latest DDR5 standard. Samsung is also cooperating with data centers and cloud providers around the world to better meet the demand for greater memory capacity, which is essential for processing big data applications including in-memory database systems.

With the commercialization of DDR5-based CXL memory modules, Samsung plans to lead the industry in meeting the demand for next-generation high-performance computing technologies that rely on expanded memory capacity and bandwidth.
