Spiking neurons with lumped nonlinearity representing active dendrites can perform a larger number of input-output mappings than is possible by a neuron with linear synaptic summation of its currents. This is possible due to the additional degree of freedom in such cells-its `morphology' reflected in the number of dendrites and the choice of which inputs(More)
This brief describes the neuromorphic very large scale integration implementation of a synapse utilizing a single floating-gate (FG) transistor that can be used to store a weight in a nonvolatile manner and demonstrate biological learning rules such as spike-timing-dependent plasticity (STDP). The experimental STDP plot (change in weight against △t =(More)
Learning in a neural network typically happens with the modification or plasticity of synaptic weight. Thus the plasticity rule which modifies the synaptic strength based on the timing difference between the pre- and post-synaptic spike occurrence is termed as Spike Time Dependent Plasticity (STDP). This paper describes the neuromorphic VLSI implementation(More)
Synapse plays an important role in learning in a neural network; the learning rules that modify the synaptic strength based on the timing difference between the pre- and postsynaptic spike occurrence are termed spike time-dependent plasticity (STDP) rules. The most commonly used rule posits weight change based on time difference between one presynaptic(More)
