“…Due to versatile properties, such as biodegradability, biocompatibility, bioresorbability, optical transparency, and light weight, proteins, the most readily accessible biomolecules can be used as an attractive building blocks for the development of RRAM devices and endow these electronic memories with excellent performance and environmental benignity 31, 32. They have been both served as an active switching component of a passive substrate to construct two‐terminal RRAM devices with impressive ON/OFF ratios, ultralow density, low operating voltage, good degradability, and tunable‐resistive switching behavior 33, 34, 35, 36, 37, 38, 39…”
