   Neuromorphic systems built from memristors that emulate bioelectrical information processing in a brain may overcome limits in traditional computing architectures. However, functional emulation alone may still not attain all the merits of bio-computation, which uses action potentials of 50-120 mV at least 10-time lower than signal amplitude in conventional electronics to achieve extraordinary power efficiency and effective functional integration. Reducing the functional voltage in memristors to this biological amplitude thus can advance neuromorphic engineering and bio-emulated integration. This review aims to provide a timely update on the effort and progress in this burgeoning direction, covering aspects in device material composition, performance, working mechanism, and potential application.

3. 25.8 A Near- Threshold-Voltage Network-on-Chip with a Metastability Error Detection and Correction Technique for Supporting a Quad-Voltage/Frequency-Domain Ultra-Low-Power System-on-a-Chip

   Emerging embedded systems, such as autonomous robots/vehicles, demand a new system-on-a-chip (SoC) that is ultra-low power (mW or even sub-mW level) but highly robust. Such an SoC typically integrates heterogeneous building blocks for supporting a range of features, each ideally operating in an independent voltage and frequency (V/F) domain [1]. In such an architecture, a network-on-chip (NoC) has played a key role to enable high-speed and energy-efficient networking. However, it is increasingly challenging to meet a robustness target since each V/F domain uses a significantly different voltage, e.g., from nominal 1V to near-threshold voltage (NTV), and clock frequency, e.g., from hundreds of MHz to sub-MHz. Furthermore, any two clocks may have uncertain and time-varying phase and frequency relationships. These properties significantly worsen robustness, particularly metastability, in an NoC.
