Abstract
Multifunctional electronic memories capable of demonstrating both analog and digital switching on-demand are extremely attractive for miniaturization of electronics without significant drain on energy consumption. Simultaneously translating functionality onto mechanically conformable platforms will further enhance their suitability. Here, we demonstrate the ability to engineer multi-functionality in strontium titanate (STO) based resistive random-access memories (ReRAM) on a flexible polyimide (PI) platform. By utilising different bottom electrodes of various work functions while the top electrode is fixed, differential work-functions are induced in STO, to induce bipolar (BP) or complementary (CS) switching behaviours whenever required. This work-functions difference induced bifunctional switching on flexible platform reveals a streamlined route for achieving flexible artificial neural networks, high density integration, and logic operation using a single ReRAM.
