A neuromorphic device includes a pre-synaptic neuron, a synapse electrically coupled to the pre-synaptic neuron through a row line, and a post-synaptic neuron electrically coupled to the synapse through a column line. The post-synaptic neuron includes an integrator, a comparator, and an error corrector including an error detector and a correction signal generator. The comparator and the error corrector receive an output of the integrator.
