Abstract: The present invention relates to a synapse and synaptic array, and a computing system using the same. The synaptic device according to an exemplary embodiment of the present invention includes a transistor in which a synaptic input signal is applied to any one electrode of source and drain electrodes; and a plurality of two-terminal variable resistance memory devices in which a first electrode is electrically globally connected to a gate electrode of the transistor, wherein a separate memory voltage is applied to a second electrode of each variable resistance memory device to adjust a gate voltage applied to the gate electrode, thereby controlling a synaptic output signal which is output to the other one of the source and drain electrodes.
