Needham: "DRAM/HBM will remain a real bottleneck for AI."

> DRAM/HBM Bottleneck: DRAM and High Bandwidth Memory (HBM) are projected to remain significant bottlenecks for AI hardware scaling.

> Rapid Bit Growth: Total DRAM bit growth (millions of GB) is expected to expand dramatically through 2028, driven heavily by increasing HBM adoption.

> Surging HBM Share: HBM bits as a percentage of total DRAM are forecasted to grow steeply, scaling past 15% by 2028.

> Wafer Capacity Shift: DRAM wafer capacity dedicated to HBM (measured in kWSPM) is projected to accelerate sharply, with expectations that nearly 50% of total DRAM wafers will go into HBM by 2028.
