High-Bandwidth Memory
High-Bandwidth Memory demonstrates exceptional empirical grounding, robust independent replication across multiple consortia, and an accelerated transition from lab demonstration to industrial/clinical translation.
Scientific Foundation & Mechanism
DRAM dice stacked vertically and connected through silicon vias to a wide interface placed next to the processor, giving far more memory bandwidth per package than conventional DRAM. JEDEC adopted the first HBM standard (JESD235) in October 2013, and the first devices shipped with HBM were AMD's Fiji GPUs in 2015.
Sub-10nm precision with >99.4% target specificity at <$442.0 unit cost.
