- Memristors pave the way for brain-inspired computing in AI systems
- Atomically adjustable devices promise energy-efficient AI processing
- Neuromorphic circuits unveil new opportunities for artificial intelligence
A groundbreaking advancement in semiconductor technology appears to be within reach, thanks to the development of atomically tunable “memristors,” which are advanced memory resistors designed to mimic the human brain’s neural network.
This initiative, backed by the National Science Foundation’s Future of Semiconductors program (FuSe2), seeks to create devices that facilitate neuromorphic computing—a cutting-edge approach that aims to achieve rapid, energy-efficient processing that parallels the brain’s learning and adaptive capabilities.
Central to this innovation is the fabrication of ultrathin memory devices with atomic-scale precision. These memristors could revolutionize AI, functioning as artificial synapses and neurons, thereby significantly enhancing both computing power and efficiency. They also promise to open new avenues for applying artificial intelligence, while simultaneously training a fresh cohort of semiconductor experts.
Challenges in Neuromorphic Computing
The project is focused on addressing a critical challenge in modern computing: achieving the precision and scalability necessary to bring brain-inspired AI systems to life. Memristors are pivotal in developing energy-efficient, high-speed networks that resemble the functions of the human brain, enabling parallel data processing akin to biological systems and potentially overcoming the constraints of traditional computing architectures.
In a collaborative research effort between the University of Kansas and the University of Houston, led by Judy Wu, a distinguished Professor of Physics and Astronomy, the initiative received a $1.8 million grant from FuSe2. Wu and her team have innovated a method to achieve sub-2-nanometer thickness in memory devices, with some film layers reaching an astonishing 0.1 nanometers—approximately ten times thinner than what is typical.
These advancements are vital for the trajectory of future semiconductor electronics, allowing for the creation of devices that are not only exceedingly thin but also highly functional, with uniform performance across large areas. Furthermore, the research team is adopting a co-design approach that intertwines material design, fabrication, and testing.
Notably, the project emphasizes workforce development, acknowledging the growing demand for skilled professionals in the semiconductor industry. Experts from both universities have established an educational outreach component to address this need.
“The overarching aim of our work is to develop atomically ‘tunable’ memristors that can serve as neurons and synapses in a neuromorphic circuit. This focus on neuromorphic computing is the cornerstone of our research,” Wu explained.
“Our goal is to replicate the brain’s ability to think, compute, make decisions, and recognize patterns—essentially emulating all the brain’s functions with remarkable speed and energy efficiency.”
