Advanced technologies for brain-inspired computing

Abstract : This paper aims at presenting how new technologies can overcome classical implementation issues of Neural Networks. Resistive memories such as Phase Change Memories and Conductive-Bridge RAM can be used for obtaining low-area synapses thanks to programmable resistance also called Memristors. Similarly, the high capacitance of Through Silicon Vias can be used to greatly improve analog neurons and reduce their area. The very same devices can also be used for improving connectivity of Neural Networks as demonstrated by an application. Finally, some perspectives are given on the usage of 3D monolithic integration for better exploiting the third dimension and thus obtaining systems closer to the brain.
