Flikker: saving DRAM refresh-power through critical data partitioning

  title={Flikker: saving DRAM refresh-power through critical data partitioning},
  author={Song Liu and Karthik Pattabiraman and Thomas Moscibroda and Benjamin G. Zorn},
Energy has become a first-class design constraint in computer systems. Memory is a significant contributor to total system power. This paper introduces Flikker, an application-level technique to reduce refresh power in DRAM memories. Flikker enables developers to specify critical and non-critical data in programs and the runtime system allocates this data in separate parts of memory. The portion of memory containing critical data is refreshed at the regular refresh-rate, while the portion… CONTINUE READING
