Biomimetic 4F2 synapse with intrinsic timescale for pulse based STDP by I-NPN selection device

Abstract

We have proposed a 4F2 synapse using I-NPN based selector with high on-off ratio as well as intrinsic timescales which are utilized to implement time correlation in a synapse for high density neuromorphic circuits. STDP based learning is demonstrated using simple pulses while is true biomimetic.
