Special Session

15.3 - Energy-Efficient DRAM for High-bandwidth Applications

10:30 AM–12:00 PM Jun 26, 2018 (America - Los Angeles)

Room 3024

High-bandwidth DRAM systems providing several TB/s of bandwidth can consume over 100W of system power. These high-bandwidth systems range from HPC compute notes to advanced autonomous systems. There are many different aspects of DRAM operation that determine the energy demand of the memory system. This talk looks at the different sources of DRAM energy consumption, application characteristics that stress different aspects, and the architectural approaches that can mitigate these factors. These techniques can significantly reduce the DRAM energy requirements in these future high-bandwidth systems, enabling a larger proportion of the power budget to be devoted to computation or reducing the overall power demand allowing battery lifetime/range in autonomous systems
