Abstract: Embodiments of inventive concepts relate to a neuromorphic circuit including a flash memory-based spike regulator capable of generating a stable spike signal with a small number of devices. The neuromorphic circuit may generate a simple and stable spike signal using a flash memory-based spike regulator. Therefore, it is possible to implement a semiconductor neuromorphic circuit at low power and low cost by using the spike regulator of the present invention. Example embodiments of inventive concepts provide a neuromorphic circuit comprising a control signal generator for generating a control signal for generating a pulse signal; and a spike regulator for generating a spike signal in response to the control signal. Wherein the spike regulator comprises a first transistor for switching an input signal transmitted to one terminal to the other terminal in response to the control signal; and a first flash memory type transistor having a drain terminal connected to the other terminal of the first transistor and transferring the switched input signal to a source terminal as a spike signal.
