Fine-Grained DRAM: Energy-Efficient DRAM for ExtremeBandwidth SystemsMike O Connor Niladrish Chatterjee Donghyuk Lee John Wilson Aditya Agrawal Stephen W. Keckler William J. Dally NVIDIA The University of Texas at Austin Stanford University{moconnor, nchatterjee, donghyukl, jowilson, adityaa, skeckler, bdally} GPUs and other high-performance throughput processors willrequire multiple TB/s of bandwidth to DRAM. Satisfying this band-width demand within an acceptable energy budget is a challengein these extreme bandwidth memory systems. We propose a newhigh- bandwidth DRAM architecture, Fine-Grained DRAM (FGDRAM),which improves bandwidth by 4 and improves the energy efficiencyof DRAM by 2 relative to the highest- bandwidth , most Energy-Efficient contemporary DRAM, High bandwidth Memory (HBM2).
