Huge demand of electronic gadgets with different form factors and applications has been driven by the needs of Internet of Things (IoT) with intelligent gadgets artificially created based on both hard and software. This is the catalyst for industrial revolution 4.0 to be spearheading. In this new era, classical computing hardware based on von Neumann architecture is the only platform that is driving sophisticated and innovative software algorithms to achieve artificial intelligence (AI) of an electronic gadget. However, humongous amount of power is needed to operate the hardware with significant energy loses if compared with a human brain performing a similar task. Since huge majority of electronic gadget is built based on non-renewable and non-sustainable type of engineering materials, another issue may be confronted, i.e. electronic waste, when gadgets are disposed. Even though their development of IoT and AI provide significant advantages to mankind by enhancing connectivity, security, comfortability, productivity, etc., energy waste and electronic waste must be seriously considered during the design stage of those gadgets. One of the strategies to simultaneously overcome these two issues is by replacing energy wastage of von Neumann based architecture in hardware computing with more energy efficient brain-like (neuromorphic) computing and replacing non-sustainable type of engineering materials to produce the hardware with bio-organic based materials that can be derived from plants, living, or once living things. In order to produce neuromorphic computing, adoption of an appropriate non-volatile memory technology is essential. Of all the technologies, resistive switching random access memory (RRAM) would be the most promising one due to multiple advantages if compared with others. The mimicking of RRAM to a biological synapse in a human brain that connect neurons for the objective of realizing a building block for a neuromorphic computing will be elaborated in this Talk. The historical development of bio-organic materials for artificial synaptic will be reviewed, mechanisms controlling the performance will be shared, and future challenges of this research will be suggested.
