Abstract

Here, a high-performance transparent flexible dynamic random access memory (DRAM) device on a polyvinyl alcohol (PVA) substrate is presented with silver nanowires (Ag NWs) serving as top and bottom electrodes, and hybrid silver nanoparticles (Ag NPs)-polyvinyl pyrrolidone (PVP) films serve as resistive-switching (RS) medium. The obtained memory cells show typical volatile RS behaviors with an ultrahigh ON/OFF current ratio of 10⁸ and an ultralow switching voltage of 0.7 V. In particular, the fabricated flexible devices demonstrate excellent mechanically robust feature and great electrical stability during 100 dynamic bending tests, maintaining ~85% of transparency in the visible wavelength. This work provides an effective route to construct flexible and transparent polymer memory devices with high-performance.
