The Quick Take
- SK Hynix revealed 'iHBM' technology embedding a proprietary ICE (Integrated Cooling Element) directly inside High Bandwidth Memory chips, reducing heat resistance by over 30%
- The ICE element uses silicon material that conducts heat but not electricity, overcoming the leading technical barrier in next-generation HBM scaling for AI computing density
- The iHBM innovation will deploy starting with HBM5 (8th generation), positioning SK Hynix to lead in AI accelerator thermal management as GPU power density continues rising
