We report wavelength-dependent characteristics in OFET memories using DNTT. Owing to photocarrier generation in floating gates, the memories exhibit V_th shifts under red LED light and emulate light-responsive synaptic characteristics. Under blue LED light, the memories exhibit nonvolatile memory characteristics and achieve good linearity of conductance change, enabling analog synaptic functions.
