Memristor technology is a promising alternative to CMOS due to its high integration density, near-zero standby power, and ability to implement novel resistive computing. One of the major limitations of these architectures is the limited endurance of memristor devices, especially when a logic gate requires multiple steps/switching to execute the logic operations. To alleviate the endurance requirement and improve the performance, we present a novel logic design style, called scouting logic that executes any logic gate by only reading the memristor devices and without changing their states. Hence, no impact on the memristors' endurance. The proposed design is implemented using two styles (current and voltage based). To illustrate the performance of scouting logic based designs, the area, delay, and power consumption are analyzed and compared with state-ofthe- art. The results show that scouting logic improves the delay and power consumption by at least a factor of 2.3, while having similar or less area overhead. Finally, we discuss the potential applications and challenges of scouting logic.@en

Many emerging technologies are under investigation to realize alternatives for future scalable electronics. Memristor is one of the most promising candidates due to memrsitor’s non-volatility, high integration density, near-zero standby power consumption, etc. Memristors have been recently utilized in non-volatile memory, neuromorphic system, resistive computing architecture, and FPGA to name but a few. An FPGA typicallyconsists of configurable logic blocks (CLBs), programmableinterconnects, configuration, and block memories. Most of therecent work done was focused on using memristor to build FPGA interconnects and memories. This paper proposes two novel FPGA implementations that utilize memristor-based CLBs and their corresponding automatic design flow. To illustrate the potential of the proposed implementations, they are benchmarked using Toronto 20, and compared with the state-of-the-art in terms of area and delay. The experimental results show that both the area (up to 4.24x) and delay (up to 1.46x) of the novel FPGAs
are very promising.@en
