Abstract

Cross-bar array organic resistive memory devices enable high storage density but suffer from the issue of undesired cross-talk. A one transistor-one resistor (1T-1R) architecture offers a potential solution to this issue. However, all organic based 1T-1R architecture has not yet been demonstrated due to the difficulties in fabrication and operational voltage range mismatching between organic resistive memory and organic transistor. Herein, we demonstrate the first all-organic based 64 bit memory cell array utilizing 1T-1R architecture. The transfer and output curves of transistors in the 1T-1R cell array are governed by the memory cell and the 64 bit array show precise addressing due to gating of transistors. Moreover, the 1T-1R cell array encoded letters based on the standard ASCII character code.
