Samsung Unveils Industry-First CXL Enabled DDR5 Module

by dhiram

Samsung today unveiled the industry’s first memory module supporting the new Compute Express Link (CXL) interconnect standard. Integrated with Samsung’s Double Data Rate 5 (DDR5) technology, this Samsung CXL-based module will enable server systems to significantly scale memory capacity and bandwidth, accelerating artificial intelligence (AI) and high-performance computing (HPC) workloads in data centers. This module will play a critical role in serving data-intensive applications including AI and machine learning in data centers as well as cloud environments, said Cheolmin Park, vice president of the Memory Product Planning Team at Samsung Electronics.


Unlike conventional DDR-based memory, which has limited memory channels, Samsung’s CXL-enabled DDR5 module can scale memory capacity to the terabyte level, while dramatically reducing system latency caused by memory caching. In addition to CXL hardware innovation, Samsung has incorporated several controller and software technologies like memory mapping, interface converting and error management, which will allow CPUs or GPUs to recognize the CXL-based memory and utilize it as the main memory.


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