Memory power management via dynamic voltage/frequency scaling

Howard David, Chris Fallin, Eugene Gorbatov, Ulf R. Hanebutte, Onur Mutlu
2011 Proceedings of the 8th ACM international conference on Autonomic computing - ICAC '11  
There are many proposals to scale energy at the datacenter and server level. However, one significant component of server power, the memory system, remains largely unaddressed.  ...  As we show, in a typical server platform, memory consumes 19% of system power on average while running SPEC CPU2006 workloads.  ...  Acknowledgments We thank the anonymous reviewers for their feedback. We gratefully acknowledge members of the Power Management Architecture group at Intel Labs.  ...
