Problems solved by technology

However, on the one hand, this kind of IMP logic is not the mainstream logic operation method. On the other hand, when the situation of realizing specific logic functions is more complicated, the number of memristors required by this technical solution is relatively large, which is not conducive to semiconductor The miniaturization of the circuit, and the complicated and lengthy operation steps affect the execution efficiency of the circuit

Abstract

The invention discloses an operation method based on a memristor array. According to the method, a logical subunit is used, wherein the logical subunit comprises at least two input units, an output unit and at least one reference unit; each input unit comprises a first input resistance change unit and a second input resistance change unit; the output unit comprises a first output resistance change unit; all units are properly connected with word lines and bit lines; specific voltage pulse is applied to the input and output resistance change units and the reference unit; the logical calculation operation and the reconfiguration are realized in a simple mode; the storage and calculation integration is realized; the number of the required memristors is reduced; the executing efficiency of logical calculation is also improved.

Description

technical field [0001] The present invention relates to the field of semiconductor integrated circuits, and more particularly relates to an operation method based on a memristor array, especially suitable for reconfigurable logic operations. Background technique [0002] In traditional computer systems, logic operations are performed by computing elements, and the results of operations are stored by memory. However, this method needs to calculate first, and then output the calculation result to the memory, and the process is relatively complicated. Memristor is a new type of device. Ideal memristor can be used not only to make memory, but also to perform logic operations, which provides the possibility of realizing the integration of computing and storage. Memristors can memorize resistance, and can be calculated by using its resistive characteristics, and the calculation results are saved in the form of the resistance state of the memristor. [0003] For example, it is de...
