We report the synaptic characteristics of poly(3-hexylthiophene)-based OFET memories with organic semiconductor floating gates composed of TIPS-pentacene. Under red light, the output current due to the storage of photogenerated electrons shows light-intensity dependent synaptic characteristics as a result of carrier generation at the organic semiconductor floating gates.
