High Bandwidth Memory (HBM)
A memory technology that achieves high bandwidth by vertically stacking multiple DRAM dies and interconnecting them with through-silicon vias; it is a core companion component for AI training and inference accelerators.
Timeline (last 90 days)
High Bandwidth Memory (HBM) stacks DRAM and widens the bus to raise bandwidth to several times that of conventional GDDR, and is therefore valued in AI servers.
High Bandwidth Memory (HBM) uses through-silicon via (TSV) technology to stack multiple layers of DRAM chips vertically, achieving extremely high bandwidth and low power consumption within a limited area.
HBM is far more difficult to manufacture than conventional memory; currently only a few manufacturers worldwide can achieve stable mass production, and capacity expansion cycles are long with enormous capital investment.
Surging demand from AI data centers for components such as high-bandwidth memory (HBM) is siphoning off large amounts of upstream capacity, tightening supply available to the PC supply chain accordingly.
