With the rising importance of energy efficiency, zero leakage power and instant-on capability are highly desired features in harvesting sensors, as well “normally off” high performance processors. However, intermittent such systems requires nonvolatile memory (NVM) to hold intermediate data avoid rollbacks. Previous work has adopted FeRAM STT-MRAM achieve zero-standby fast-restore processors (NVPs) [1–3]. NVPs, however, suffer from several drawbacks: 1) Various interrupt periods not...
