Recently, the lifetime of electronic devices has decreased to just about several months[1]. The disposal of these unused electronics constitutes the steep rising electronic waste (E-waste), which is currently over 50 million tons per year[2]. The solution to this problem lies in the total transformation of the electronics industry and the adoption of “Green electronics” ideas. In this work we present emerging memory devices fabricated using biological materials such as chitosan[3-5] and cow milk as the active layers. These devices are emerging, and thus have better functionality compared to the current memory giants, i.e., dynamic random-access memory (DRAM) and Flash memories. Furthermore, these devices have shown compatibility with on-chip computing (Neuromorphic computing). Our devices were fabricated in electricity- and heat-free processes and have low power consumption prospects. Therefore, they adhere to environmental regulations and green computing ideas.
Zolile is a lecturer at Central University of Technology. He recently finished and awaiting graduation with a Ph. D in Physics at the University of South Africa (UNISA) where he is supervised by Prof. SV Vallabhapurapu (UNISA) and Dr S Vallabhapurapu (UNISA) and Dr. S Wu (Macquarie University, Australia). He has a first-class MSc in physics (UNISA) and he currently holds both the new generation of academics program (nGAP) (Department of higher education and training (DHET), ZA) and national research foundation (NRF-ZA) grants for his Ph.D studies. He has operational expertise in electron spin resonance (ESR), atomic force microscope (AFM), electronic characterization using the Keysight SMU, and many more. His research experience includes low-temperature physics where he did research on superconductivity. Zolile is currently working on developing biodegradable resistive switching memory (ReRAM) using biological/organic materials. He is fascinated with the idea of dissolvable, flexible, and disposable electronics devices.
