Wafer-Scale Ag₂S-Based Memristive Crossbar Arrays with Ultra-Low Switching-Energies Reaching Biological Synapses.

ABSTRACT: Memristive crossbar arrays (MCAs) offer parallel data storage and processing for energy-efficient neuromorphic computing. However, most wafer-scale MCAs that are compatible with complementary metal-oxide-semiconductor (CMOS) technology still suffer from substantially larger energy consumption than biological synapses, due to the slow kinetics of forming conductive paths inside the memristive units. Here we report wafer-scale Ag₂S-based MCAs realized using CMOS-compatible processes at temperatures below 160 °C. Ag₂S electrolytes supply highly mobile Ag⁺ ions, and provide the Ag/Ag₂S interface with low silver nucleation barrier to form silver filaments at low energy costs. By further enhancing Ag⁺ migration in Ag₂S electrolyte
