Abstract :
This paper establishes that adapting the DRAM row buffer policy in accordance with both locality and activity in memory access patterns can lead to significant reductions in DRAM energy. In particular, using two different enterprise workloads, we establish that a spatially and temporally adaptive row buffer timeout policy is more energy-efficient than any static policy. Our results show that energy can be reduced by 6% and 30% for the two enterprise workloads.
