Active Low-Power Modes for Main Memory with MemScale
Qingyuan Deng, Luiz Ramos, Ricardo Bianchini, David Meisner, Thomas F. Wenisch · IEEE Micro · 2012
Main memory accounts for a growing fraction of server energy usage. Investigating active low-power modes for managing main memory, with a system called MemScale, the authors offer a solution for performance-aware energy management. By creating a set of low-power modes, hardware mechanisms and software policies, MemScale trades memory bandwidth for energy savings while tightly limiting the associated performance impact.
