Patent number: 8017939Abstract: The present disclosure relates to an organic memory device and a fabrication method thereof. The organic memory device comprises a first electrode, a second electrode, and an organic memory layer situated between the electrodes, wherein a metallic nanoparticle layer is further situated between the first electrode and the organic memory layer. Since the organic memory device may be operated using only positive voltages, a 1D1R device composed of one diode and one resistor can be realized and a passive matrix can be realized due to the 1D1R structure. Accordingly, the organic memory device enables higher integration, ultrahigh speeds, larger capacities, lower power consumption, and/or lower prices.Type: GrantFiled: April 24, 2007Date of Patent: September 13, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Won Jae Joo, Seong Jae Choi, Jae Young Choi, Sang Kyun Lee, Kwang Hee Lee
