This review paper mainly introduces memory devices (RRAM and FET) composed of different biocomposites with biocompatibility, flexibility and biodegradability. On this basis, the progress of artificial synapses to mimic biological synapses is discussed and the future development of green electronic devices is presented. Reprinted with permission from [28].
