一种忆阻扫描触发器设计
Design of scan flip-flop based on memristor

基于惠普公司的忆阻器模型，提出一种可支持断电模式的选择扫描触发器电路. 数据可以从主从触发器中被传输存储到忆阻器中，在触发器被断电期间，忆阻器一直保持该数据. 当扫描触发器处于唤醒时刻，忆阻器所保持的数据可以被控制回传到主从触发器中. 采用惠普公司提供的忆阻器模拟电路仿真模型进行仿真验证，仿真数据及波形表明，该电路可以满足集成电路的低功耗扫描测试需求.
In this paper，we study the characteristics of memristor，a multiplexed flip-flop model based on memristor is proposed which can support power-off mode for scan testing. Data in the master-slave flip-flop can be stored into the memristor，the memristor hold the data during the time of total memristive multiplexed flip-flop is cut off from the power line. At the wake up time，data in the memristor can be recalled back to the master-slave flip-flop. Signal waveforms of the simulation results show that the presented memristive multiplexed flip-flop meet the requirements for low-power scan testing
