Abstract
An operation method for integrating logic calculations and data storage based on a crossbar array structure of resistive switching devices. The calculation and storage functions of the method are based on the same hardware architecture, and the data storage is completed while performing calculation, thereby realizing the fusion of calculation and storage. The method includes applying a pulse sequence to a specified word line or bit line by a controller, configuring basic units of resistive switching devices to form different serial-parallel structures, such that three basic logic operations, i.e. NAND, OR, and COPY, are implemented and mutually combined on this basis, thereby implementing 16 types of binary Boolean logic and full addition operations, and on this basis, a method for implementing a parallel logic and full addition operations is provided.
