December 27, 2023 by our News Team

Samsung Electronics and Red Hat have successfully verified Compute Express Link (CXL) memory operations in a real user environment, marking a major milestone in expanding Samsung's CXL ecosystem and addressing the growing need for systems with greater memory bandwidth and capacity.

  • Successful verification of CXL memory operations in a real user environment
  • Collaboration with open-source software provider Red Hat to expand CXL ecosystem
  • Optimization of CXL memory for Red Hat Enterprise Linux and seamless integration into existing hardware


Samsung Electronics, a global leader in advanced memory technology, has made a significant breakthrough in the industry by successfully verifying Compute Express Link (CXL) memory operations in a real user environment. This achievement was made possible through a collaboration with open-source software provider Red Hat, marking a major milestone in expanding Samsung’s CXL ecosystem.

With the rapid growth of data throughput and memory requirements in emerging fields such as generative AI, autonomous driving, and in-memory databases, there is a pressing need for systems with greater memory bandwidth and capacity. CXL, a unified interface standard, addresses these demands by connecting various processors, including CPUs, GPUs, and memory devices, through a PCIe interface. It offers a solution to the limitations of existing systems in terms of speed, Latency, and expandability.

YongCheol Bae, Executive Vice President of Memory Product Planning at Samsung Electronics, expressed the company’s commitment to building the CXL memory ecosystem through collaborations with industry partners in software, data centers, servers, and chipset providers. The partnership with Red Hat is a prime example of the collaboration between advanced software and hardware that will enhance and accelerate the CXL ecosystem.

Samsung has optimized its CXL memory for Red Hat Enterprise Linux (RHEL) 9.3 and successfully verified memory recognition, read and write operations in Red Hat’s KVM and Podman environments. This means that data center clients can seamlessly integrate Samsung’s CXL memory into their existing hardware without the need for additional adjustments.

Marjet Andriesse, Senior Vice President and Head of Red Hat Asia Pacific, highlighted the significance of this achievement, stating that it expands the applicability of the CXL Memory Expander to IaaS and PaaS-based software provided by Red Hat. This breakthrough represents a crucial step towards integrating hardware and software to create an open-source ecosystem for next-generation memory development.

Samsung and Red Hat are currently collaborating on a “RHEL 9.3 CXL Memory Enabling Guide” to assist users in leveraging Samsung’s CXL memory on RHEL 9.3 and building high-performance computing systems across various user environments.

This partnership between Samsung and Red Hat began with a memorandum of understanding (MOU) signed in May 2022, focusing on next-generation memory development. The collaboration will continue through the Samsung Memory Research Center (SMRC), with a specific focus on developing CXL open-source and reference models. The partnership covers a wide range of storage and memory products, including NVMe SSDs, CXL Memory, computational memory/storage, and fabrics.

Technology Explained


Latency: Technology latency is the time it takes for a computer system to respond to a request. It is an important factor in the performance of computer systems, as it affects the speed and efficiency of data processing. In the computer industry, latency is a major factor in the performance of computer networks, storage systems, and other computer systems. Low latency is essential for applications that require fast response times, such as online gaming, streaming media, and real-time data processing. High latency can cause delays in data processing, resulting in slow response times and poor performance. To reduce latency, computer systems use various techniques such as caching, load balancing, and parallel processing. By reducing latency, computer systems can provide faster response times and improved performance.


NVMe: Non-Volatile Memory Express (NVMe) is a newly developed technology that has been gaining traction in the computer industry. This technology is a standard interface which allows for high-speed storage and retrieval of data from solid state drives (SSDs). NVMe is designed to increase the speed of data transfers in storage systems by enabling a direct connection to PCI Express (PCIe) bus, resulting in significantly faster access times compared to traditional interface protocols such SSDs. NVMe is particularly useful for applications that require lightning-fast access to large amounts of high-value data. NVMe-based SSDs are being widely adopted in the computer industry and are being employed to power data centers, high-end workstations, and gaming machines to support lightning-fast data processing and retrieval, which unlocks possibilities for machine learning, real-time analytics, edge computing, and other cutting-edge applications. NVMe is proving to be an invaluable tool in the field of computing, offering immense


PCIe: PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard for connecting components such as graphics cards, sound cards, and network cards to a motherboard. It is the most widely used interface in the computer industry today, and is used in both desktop and laptop computers. PCIe is capable of providing up to 16 times the bandwidth of the older PCI standard, allowing for faster data transfer speeds and improved performance. It is also used in a variety of other applications, such as storage, networking, and communications. PCIe is an essential component of modern computing, and its applications are only expected to grow in the future.
