Revolutionary Cooling Technology Boosts SK hynix's HBM Performance

SK hynix has unveiled a groundbreaking technical solution aimed at solving one of the most pressing challenges in advancing high-bandwidth memory (HBM) for artificial intelligence workloads: excessive heat production. According to a report by The Korea Herald, the South Korean chipmaking giant has developed an advanced packaging technology called iHBM that incorporates cooling channels directly into HBM chips.

This innovative approach addresses the increasing thermal challenges faced by HBM as stacks become more extensive and operate at faster speeds, intensifying the heat generated. By embedding silicon-based cooling elements adjacent to the hotspot between the memory and processor, the system efficiently dissipates heat without disrupting electrical pathways. SK hynix reports that this design reduces thermal resistance by over 30% while maintaining consistent performance under high-temperature and high-load conditions.

Lee Kang-wook, Head of Package Development at SK hynix, emphasized that the iHBM provides an optimal solution for heat management by merging memory design expertise with the latest packaging advancements. Compatible with current customer designs, it lowers the barrier to adoption by not necessitating significant architectural changes. The company plans to initiate the use of iHBM with the HBM5 generation anticipated around 2029, aiming to meet growing demands that exceed its current production capacity. This move coincides with market competition as SK hynix faces evolving challenges in the global memory landscape.
