The Memory Crunch Is Here. Modern Architectures Are the Way Out

AI-driven data centers are hitting a memory bottleneck as DRAM prices surge 170% year‑over‑year and DDR5 spot costs have tripled since late 2025. Traditional server designs that simply add more DIMMs can no longer keep pace because high‑capacity modules are prohibitively expensive and supply‑constrained. The industry is turning to shared and disaggregated memory architectures, notably CXL, to pool resources and improve utilization. Innovative switch fabrics like XConn's UIOT allow GPUs to tap these memory pools directly, bypassing CPU bottlenecks and enabling terabyte‑scale AI workloads.
