SK hynix unveils 'iHBM' thermal architecture that cools AI memory at the source — integrated cooling elements inside HBM interface cut thermal resistance by 30%, target next-gen HBM5 accelerators and dense AI data centers
SK hynix has unveiled iHBM, a new thermal packaging architecture that embeds cooling elements directly into the HBM interface layer, reducing thermal resistance by 30% and helping future AI accelerators avoid performance-killing thermal throttling.
The exponential demand for AI compute is rapidly hitting thermal limits in current HBM technology, necessitating innovative cooling solutions to sustain performance gains.
This development addresses a critical bottleneck in AI innovation, enabling higher performance and density for next-generation AI accelerators and data centers, impacting the entire AI supply chain.
Integrated cooling at the HBM interface will allow for denser, more powerful AI chips, shifting the design paradigm for high-performance computing hardware.
