Description

technical field [0001] The embodiments of the present application relate to the technical field of storage-computing integrated chips, and in particular, to a storage-computing integrated computing method, a memristor neural network chip, and a storage medium. Background technique [0002] In recent years, the field of artificial intelligence has made great strides through the use of deep learning. There is an unavoidable data exchange between storage units and computing units at the architecture level of artificial intelligence chips. [0003] At present, the memristor memory-computing integrated architecture is usually used to eliminate the data movement between the computing unit and the storage unit in the traditional von Neumann architecture. However, there is a large analog-to-digital conversion overhead in the data movement process of the memory-computing integrated chip of the memristor and greatly limits the energy efficiency of the chip.
