The chip fuses DRAM directly beneath the compute and removes the PHY to achieve SRAM-class bandwidth while using 1/10th the power of HBM. d-Matrix claims the architecture provides a 10x speed advantage over GPUs and 10x the bandwidth of HBM4. The design aims to resolve the AI memory wall by increasing bandwidth density and reducing power consumption compared to traditional high-bandwidth memory solutions.Why it mattersGenerative AI inference is currently limited by the memory wall, where data movemen
