The physically separated memory and logic units in traditional von Neumann computers place essential limits on the performance and cause increased energy consumption, and hence in-memory computing is required to overcome this bottleneck. Here, a new bipolar memristor based in-memory logic approach is proposed, which is capable of achieving all 16 possible Boolean logic functions in a single device in less than 3 steps. This approach does not require initialization and can facilitate logic cascading, and the calculation taking place in-situ is showcased by 1-bit full adder and 2-bit multiplier with improved efficiency, thus showing a great prospect in future in-memory computing architecture.

传统的冯·诺依曼计算机中物理上分开的内存和逻辑单元对性能造成了本质限制，并导致能耗增加，因此需要使用内存中计算来克服这一瓶颈。在此，提出了一种新的基于双极忆阻器的内存中逻辑方法，该方法能够在少于3个步骤的情况下在单个器件中实现所有16种可能的布尔逻辑功能。这种方法不需要初始化，并且可以促进逻辑级联，并且通过提高效率的1位全加器和2位乘法器展示了就地进行的计算，因此在未来的内存计算体系结构中显示了广阔的前景。
