Many electronic devices today rely on semiconductor logic circuits based on hard-wired switches to perform predefined logic functions
Unlike standard hard-wired circuits, molecular devices can be reconfigured using voltage to embed different computing tasks
"This work is our major breakthrough in designing low-energy computing
The research was first published in the journal Nature on September 1, 2021
Brain-inspired technology
This new discovery contributes to the development of edge computing.
Similar to the flexibility and adaptability of human brain connections, our memory devices can be dynamically reconfigured for different computing tasks by simply changing the applied voltage
The conceptualization and molecular design system belongs to the chemical family of phenylazopyridines, an organic molecule with a central metal atom called a ligand

Using an imaging technique called Raman spectroscopy, the spectral features in the vibrational motion of organic molecules are observed to explain the multiple transitions
Researchers use decision tree algorithms with "if-then-other" sentences to describe the behavior of molecules.
New possibilities for energy-saving equipment
Based on their research, the team used molecular storage devices to run programs to complete different real-world computing tasks
"This technology may first be applied to handheld devices, such as cell phones and sensors, and other applications with limited power
The team is building new electronic devices, combining their innovations, and collaborating with collaborators to conduct simulations and benchmark tests related to existing technologies
Other authors of the research paper include Abhijeet Patra and Santi Prasad Rath of the National University of Singapore, Rajib Pramanick of the Indian Society for the Development of Science, Martin Foltin of Hewlett-Packard Company, Damien Thompson of the University of Limerick, and T.
