With the recent upsurge of data-driven technology, the demand for storage elements has pushed the researchers to explore design of nobel nonvolatile memory devices with diverse functionalities. However, the management of electronic waste has become a prominent challenge due to the rapid growth of the solid-state electronics industry. Biomaterial-based Resistive Random Access Memory (Bio-RRAM) has become one of the most promising devices that can augment the quality of memory devices because of their environmentally benign behavior, biocompatible, nontoxic, transient, transferable, flexible, dissolvable, and biodegradable nature. In this work, we report the fabrication of MIM-structured RRAM devices based on two biomaterials, namely, ovalbumin liquid and acemannan polysaccharide gel, as switching layers. Further, they are characterized by several analytical techniques. The electrical transport measurement revealed bipolar resistive switching behavior, sustainable over 1000 consecutive cycles. The devices demonstrated supreme endurance over 1000 switching cycles with a maximum ON/OFF ratio of ∼10
