Improving Energy Efficiency of Write-asymmetric Memories by Log Style Write

Provided by: Association for Computing Machinery Topic: Storage Format: PDF
The significant scaling challenges of conventional memories, i.e., SRAM and DRAM, motivated the research on emerging memory technologies. Many promising memory technology candidates, however, suffer from a common issue in their write operations: the switching processes at different write operations are asymmetric. Using a pessimistic design corner to cover the worst case of a write operation incurs large power and performance cost in the existing emerging memory technology designs. In this paper, the authors propose a universal log style write methodology to mitigate this asymmetry issue by operating two switching processes in separate stages.
