Stacking Chips Sideways Gives AI More Memory

Share

HBM is hitting thermal limits, so sideways-stacked memory is a reminder that AI scale is now gated by packaging and heat, not just transistor counts. If your roadmap assumes linear HBM gains, start scenario-planning around packaging-driven performance plateaus and more heterogeneous memory hierarchies.
