Description

technical field [0001] The invention relates to the technical field of spin electronics, and more specifically relates to a spin-storage-computing integrated chip. Background technique [0002] In the traditional von Neumann computing architecture, the memory and the processor are separated, and the two are connected through a data bus, and data processing needs to be transmitted back and forth between the memory and the processor. However, with the rise of big data applications, the transmission and processing of massive data makes the traditional von Neumann computing architecture face the dual challenges of bandwidth and power consumption, which are called storage wall and power consumption wall respectively. In order to solve these two problems, in recent years, inspired by the simultaneous memory and calculation of synapses in the human brain, the Processing-In-Memory (PIM) technology in computer architecture has begun to be widely studied. The traditional integration ...
