With the advent of the big data era and the increasingly in-depth study of the human brain system
the field of neuromorphic computing has made breakthrough progress
offering hope to break through the performance issue of traditional computers at the root level. Neural synapses are important basic units for memory training and data processing in the human brain
therefore
it is of great significance for research on neural morphological devices and the implementation of neuromorphic hardware design to develop new materials and structures to study the plasticity of neural synapses based on novel artificial materials and optoelectronic devices. This paper firstly points out the main performance issue of Von Neumann architecture
draws forth the concept of brain-like computing
puts forward the main performance advantages of neuromorphic devices
and sorts out the development history of neuromorphic devices. Then in the field of memristors
the types of memristors
memristor structures and memristor mechanisms are described and analyzed
the advantages and disadvantages of several types of memristors are compared
and the examples of applications of memristors in different fields are presented. Next
based on neural morphological devices
the structures
working principles and applications of magnetic tunnel junctions
new floating gate transistors
and ferroelectric transistors are selected to introduce. Finally
this paper summarizes the achievements and directions of the current development of neural morphological devices and predicts the development prospects of the industry.
