  • Publication number: 20230267318
    Abstract: Provided is a neuromorphic system for synaptic learning in a spiking neural network (SNN)-based neuromorphic array structure. Control blocks including a post-synaptic neuron, which generates a post-neuron spike, are disposed on output lines of a synapse array to implement a spike timing dependent plasticity (STDP) operation such that synaptic learning can be stably implemented in an SNN neuromorphic array. Also, a lateral inhibition circuit may be added. When a post-neuron spike is generated by an STDP control block connected to any one output line, the lateral inhibition circuit inhibits STDP control blocks connected to other output lines from generating spikes. Accordingly, learning selectivity can be improved, and thus the performance of an STDP algorithm can be improved.
