SK Hynix announced on April 23 the completion of customer certification for its compute express link (CXL)-based DRAM solution, specifically the CXL Memory Module (CMM)-DDR5 96-gigabyte (GB) product. This development marks a significant step in enhancing data center efficiency and performance, promising substantial improvements in capacity and bandwidth.
The newly certified CXL Memory Module is designed to improve server systems by increasing their capacity by 50% compared to existing DDR5 modules. Additionally, it expands the product’s bandwidth by 30%, enabling it to process an impressive 36GB of data per second. The company emphasized that this innovation could significantly reduce the total cost of ownership (TCO) for customers who build and operate data centers.
CXL is an open standard interconnect designed to improve communication between CPUs, GPUs, and memory. It facilitates efficient data sharing and supports large-scale, ultra-high-speed computations, making it essential for modern computing environments.
In addition to the 96GB module, SK Hynix is actively working on certifying its 128GB product with other customers. This larger module is equipped with 32-gigabit (Gb) DDR5 DRAM and utilizes a cutting-edge 10nm class 5th generation (1b) microprocessing technology. The company highlights its excellent power efficiency, which indicates the data capacity processed per second per unit of power.
SK Hynix plans to complete the certification of the 128GB product promptly and aims to establish a portfolio that can supply these products in a timely manner as per customer demand. The company is accelerating efforts to expand the ecosystem related to CXL DRAM development, ensuring they remain at the forefront of semiconductor innovation.
This announcement follows SK Hynix’s previous achievement in September of last year, when they independently developed optimized software known as “HMSDK.” This software was successfully integrated into Linux, the world’s largest open-source operating system, underscoring SK Hynix’s commitment to advancing open-source platforms in modern computing.
