Why is everyone eyeing 3D DRAM?

Multiple semiconductor companies are adopting 3D stacked DRAM technology in AI inference accelerators to achieve high performance, lower power consumption, and deterministic access. d-Matrix's Raptor accelerator showcases this with a chiplet design stacking DRAM on compute chips, achieving over 100 TB/s bandwidth and much higher capacity than SRAM-based accelerators.
