Near-threshold voltage computing promises an order of magnitude improvement in energy efficiency, enabling future processors to integrate 100s of cores running concurrently. However, such low voltage operation accompanies extreme parametric variations, resulting in unreliable operation of the processor. The memory bit-cells in on-chip caches are most vulnerable to failure due to their tight functionality margins. In this paper we focus on the NTV challenges with the last-level cache (LLC… CONTINUE READING
