Disclosed is a single transistor with a double gate structure for an adjustable firing threshold voltage and a neuromorphic system using the same. A single transistor neuron with a double gate structure according to an example embodiment includes a barrier material layer formed on a semiconductor substrate and comprising a hole barrier material or an electron barrier material; a floating body layer formed on the barrier material layer; a source and a drain formed at both sides of the floating body layer, respectively; a driving gate formed at a first side of the floating body layer without contacting the source and the drain; a control gate formed at a second side of the floating body layer without contacting the source and the drain; and a gate insulating film formed between the floating body layer and the driving gate and between the floating body layer and the control gate.
