Researchers turn HBM on its side to tackle AI memory’s heat wall — Korean V-Die and Japanese MOSAIC designs promise higher bandwidth, denser stacks, and cooler future GPUs

Scientists in Korea and Japan have introduced innovative sideways-stacked DRAM designs, known as V-Die and MOSAIC, which could revolutionize AI memory systems by addressing the heat issues plaguing traditional high-bandwidth memory (HBM). These new designs promise to enhance bandwidth, increase memory density, and cool GPUs more effectively. This breakthrough could lead to more powerful and efficient AI applications, making it a significant step forward in the tech world's ongoing battle against thermal limitations in memory technology.
