SK hynix announced on the 23rd that it has completed customer certification for its CXL 2.0-based DRAM solution CMM (CXL Memory Module)-DDR5 96GB (gigabyte) product.
CXL is a next-generation solution that efficiently connects the central processing unit (CPU), graphics processing unit (GPU), and memory within computing systems to support large-scale, ultra-high-speed calculations. It is based on the PCIe interface, offering fast data transfer speeds and the pooling capability that allows for efficient memory utilization.
SK hynix said, 'Applying this product to server systems will increase capacity by 50% compared to existing DDR5 modules, and the product's bandwidth will also expand by 30%, allowing for the processing of 36GB of data per second.' This, they noted, could significantly reduce the total cost of ownership for customers building and operating data centers.
The company is also conducting certification procedures for a 128GB product with other customers following the certification of the 96GB product. This product is equipped with 32Gb (gigabit) DDR5 DRAM using a 10-nanometer-class 5th generation (1b) fine process. As a result, the energy efficiency ratio, which indicates data capacity processed per unit of power, is high.
SK hynix plans to complete this certification soon to establish a portfolio capable of supplying products on time as desired by customers.
In addition to developing CXL DRAM, SK hynix is also working to expand the CXL ecosystem. The company has developed its own optimized software, HMSDK, for this product. This proprietary software tool for heterogeneous memory allows for efficient cross-arrays between DRAM modules and CMM-DDR5, broadening bandwidth and improving system performance by relocating data to suitable memory devices based on usage frequency.
HMSDK was integrated into the world's largest open-source operating system, Linux, last September, improving the performance of systems that apply CXL.
