A standout feature of the HBM exhibit, which covers the developmental history of the product, is an art installation illustrating the high capacity of the 12-layer HBM3E compared with the world’s first DRAM from 1970. It uses grains of rice to visually convey the dramatic leap in memory technology driven by SK hynix’s technological prowess.

To the left of the HBM exhibition zone, a dedicated space is showcasing next-generation AI memory technologies including PIM and CXL.

The PIM zone features AiM and AiMX products

The PIM section introduces SK hynix’s AiM⁵ product and the AiMX accelerator card. Combining multiple GDDR6-AiM chips, AiMX is a high-speed, low-power, cost-effective memory solution which can perform computational functions—making it optimized for generative AI applications.

⁵Accelerator-in-Memory (AiM): SK hynix’s PIM semiconductor product, which features the GDDR6-AiM.

CMM-DDR5 and CMM-Ax are on display in the CXL zone

In the CXL section, SK hynix is presenting its CMM (CXL Memory Module)-DDR5⁶ which expands system bandwidth by up to 50% and capacity by up to 100% compared to systems equipped with only DDR5. A sample of CMM-Ax⁷, which integrates machine learning and data filtering functions into CXL memory, is also on display. A live demonstration of a system equipped with CMM-Ax highlights its exceptional performance.

⁶CXL Memory Module-DDR5 (CMM-DDR5): A next-gen DDR5 memory module based on CXL that enhances system bandwidth, speed, and performance for AI, cloud, and high-performance computing.
⁷CXL Memory Module-Ax (CMM-Ax): A high-performance memory module optimized for computational workloads, improving AI and data center efficiency.

To the right of the HBM exhibition, SK hynix is displaying AI solutions for servers and on-device applications.

AI solutions for servers, including DDR5 RDIMM, are also being showcased

These include products gaining attention in the high-performance computing (HPC) market such as the world’s first 1cnm DDR5 RDIMM and DDR5 MCR DIMM. The DDR5 products are showcased alongside a lineup of enterprise SSDs (eSSDs) compatible with various server form factors.

The 1cnm DDR5 RDIMM, first revealed at the TSMC Open Innovation Platform (OIP) Ecosystem Forum in September 2024, offers 11% faster operating speeds and over 9% improved power efficiency compared to the previous generation. When applied to data centers, the product is expected to reduce operational costs by up to 30%.

The on-device AI exhibition includes key products such as LPCAMM2 and ZUFS 4.0
