Abstract: A semiconductor channel based neuromorphic synapse device 1 including a trap-rich layer may be provided that includes: a first to a third semiconductor regions which are formed on a substrate and are sequentially arranged; a word line which is electrically connected to the first semiconductor region; a trap-rich layer which surrounds the second semiconductor region; and a bit line which is electrically connected to the third semiconductor region. When a pulse with positive (+) voltage is applied to the word line, a concentration of electrons emitted from the trap-rich layer to the second semiconductor region increases and a resistance of the second semiconductor region decreases. When a pulse with negative (−) voltage is applied to the word line, a concentration of electrons trapped in the trap-rich layer from the second semiconductor region increases and the resistance of the second semiconductor region increases.
