Modeling and simulation of spiking neural networks with resistive switching synapses

Artificial intelligence (AI) has recently reached excellent achievements in the implementation of human brain cognitive functions such as learning, recognition and inference by running intensively neural networks with deep learning on high-performance computing platforms. However, excessive computational time and power consumption required for achieving such performance make AI inefficient compared with human brain. To replicate the efficient operation of human brain in hardware, novel nanoscale memory devices such as resistive switching random access memory (RRAM) have attracted strong interest thanks to their ability to mimic biological learning in silico. In this chapter, design, modeling and simulation of RRAM-based electronic synapses capable of emulating biological learning rules are first presented. Then, the application of RRAM synapses in spiking neural networks to achieve neuromorphic tasks such as on-line learning of images and associative learning is addressed.
