A novel floating‐gate synapse circuit is designed to update the weight in spike time dependent plasticity (STDP) system. The update of the weight is implemented through tunnelling and injection mechanisms using floating‐gate metal–oxide semiconductor field‐effect transistors. The importance of this circuit is for obtaining a storage mechanism for synaptic strength to implement the learning signal processing application on silicon. A novel floating‐gate synapse circuit and a new integrate‐and‐fire neuron model are described to implement weight updating in a STDP system.
