Reconfigurable nonvolatile logic within the crossbar array provides a promising approach for constructing a non-von Neumann architecture that integrates computation and storage. In this paper, a nonvolatile Boolean logic configuration based on one-transistor-one-memristor (1T1M) cells is presented. The proposed logic configuration is able to execute diverse Boolean logic operations simply by altering the applied voltage level. The logic design can be mapped to the 1T1M array, and the operation results can be stored in situ. Because of the high flexibility of the logic configuration, the 1T1M array can be configured to perform the encryption and decryption of binary images. The 1T1M array can be also used to realize composite logic functions. Furthermore, the impact of resistance variation on logic operations is taken into consideration, showing strong robustness. Simulation results demonstrate the feasibility of the proposed reconfigurable nonvolatile logic design.

交叉开关阵列中的可重新配置非易失性逻辑为构建集成计算和存储的非冯·诺依曼架构提供了一种有前途的方法。本文提出了一种基于一晶体管一忆阻（1T1M）单元的非易失性布尔逻辑配置。所提出的逻辑配置能够简单地通过改变施加的电压电平来执行各种布尔逻辑运算。逻辑设计可以映射到1T1M阵列，并且运算结果可以就地存储。由于逻辑配置的高度灵活性，因此可以将1T1M阵列配置为执行二进制映像的加密和解密。1T1M阵列还可用于实现复合逻辑功能。此外，还考虑了电阻变化对逻辑运算的影响，显示出强大的鲁棒性。仿真结果证明了所提出的可重构非易失性逻辑设计的可行性。
