Emerging nonmemory technologies have been widely employed in intermittently powered the Internet of Things (IoT) devices to bridge program execution across different power cycles. Together with register contents, the cache contents will be checkpointed to nonvolatile memory upon power outages. While pure nonvolatile memory-based cache is an intuitive option, it suffers from inferior performance du...
