[0058] Implementation example 7. The present invention provides an organic transistor storage device that realizes bipolar storage through light assistance, and the device structure is Si / SiO 2 (300nm) / Pinmill Lattice I(10nm) / Pentacene(50nm) / Cu. The device includes: a gate, an insulator, a dielectric, a hole transport layer, a source, and a drain. The gate is made of Si, and the insulator is made of SiO with a thickness of 300nm. 2 , the dielectric uses MC with a thickness of 10nm 3 , the thickness of the hole transport layer Pentacene is 50nm, the source and the drain are made of Cu, and an organic transistor memory device with good memory performance is obtained. At a negative (-80V) gate voltage, a memory window of 35.52V is achieved. Under positive (80V) gate voltage and light, a storage window of 20.15V is realized. On / off ratio remains at 10 after 10000 seconds 3 above.
