【Abstract】 Nonvolatile logic is considered as one of the most promising candidates for non-von Neumann computing architecture, which can achieve in-memory computing from the device level and thus mitigate the limitations in terms of performance and energy consumption as a result of the frequent data movement. Memristor has significant advantages in implementing nonvolatile logic due to its fast operation speed, high scalability, high endurance, and CMOS compatibility. This article provides an overview on recent status and progress in memristor based nonvolatile logic. We summarize the existing logic approaches and evaluate their respective advantages and disadvantages. Critical factors that impact the overall performance are analyzed from the device and array levels, and possible optimization strategies are suggested. Finally, we discuss future prospect of nonvolatile logic based on memristors in next-generation computing technologies.更多还原
