The physical memory wall forces AI chip design to abandon raw capacity for optical routing.
Faced with persistent shortages of high-bandwidth memory, semiconductor developers must redesign their architectures to offload storage tiers and rely on high-speed optical interconnects.

The convergence
The same conclusion keeps arriving from across the workspace's research — 1 topics independently instantiate this theme. Filter the evidence by where it came from:
AI Infrastructure Spending
Nvidia: Record $235B Buyback, Morgan Stanley Top Pick, and Rubin at 20% of Data Center Revenue Tight supply of high-bandwidth memory is actively limiting the physical storage limits of next-generation accelerators.
AI Infrastructure Spending
NVIDIA Adapts Vera Rubin Platform to Navigate HBM Shortage and "Despec" Risks The memory wall is answered by offloading the KV cache to storage tiers and routing through optics rather than adding raw HBM capacity.
