Flexible and twistable all organic non-volatile memory cell array with one diode-one resistor architecture |
| 초록 |
In this work, we fabricate UV-patterned and vertically-stacked 64-bit 1D-1R memory cell arrays using P3HT diodes and a mixture of polystyrene (PS) and 6-phenyl-C61 butyric acid methyl ester (PCBM) for the memory components on polyethylene naphthalate (PEN) flexible substrates at low temperature. Each individual memory and diode device in the integrated memory cell worked without malfunction. The 64-bit 1D-1R memory cell arrays also show stable memory characteristics (ION/IOFF ratio ~103) and reliable retention times (104 seconds) and endurance cycles (102 cycles) after substrate deformation. In addition, the issue of undesired cross-talk between neighboring cells is solved by integrating the organic diodes directly on top of the organic memory cells. No cross-talk is observed after various mechanical deformations of the flexible substrate. |
