In what sounds like science fiction, researchers are now growing computer components from mushrooms. According to recent findings from The Ohio State University, common edible fungi like shiitake mushrooms can be trained to act as memory chips, potentially revolutionizing how we build sustainable computing systems.

The Fungal Computing Revolution
Sources familiar with the research indicate that mushroom-based memristors demonstrate similar memory effects to traditional semiconductor chips. These organic devices can remember past electrical states, functioning much like the memristors used in conventional computing but with a crucial environmental advantage: they’re biodegradable.
Industry analysts suggest this breakthrough couldn’t come at a better time. “Being able to develop microchips that mimic actual neural activity means you don’t need a lot of power for standby or when the machine isn’t being used,” lead researcher John LaRocco reportedly noted in the study. “That’s something that can be a huge potential computational and economic advantage.”
Surprising Performance Metrics
What’s particularly striking about these findings is how well the mushroom memristors performed under testing. Reports from the research team show that when used as RAM—the computer memory that stores active data—their fungal creation could switch between electrical states at up to 5,850 signals per second with approximately 90% accuracy.
Performance did decline as electrical frequency increased, but researchers discovered an elegant solution: much like an actual brain, the system could be improved by connecting more mushrooms to the circuit. This neural-network approach suggests fascinating possibilities for scalable organic computing.
The methodology itself was surprisingly straightforward. Researchers cultured samples of shiitake and button mushrooms, dehydrated them for longevity, then connected them to electronic circuits. “Depending on the voltage and connectivity, we were seeing different performances,” LaRocco explained in the published study.
Sustainable Computing’s New Frontier
This research arrives as the tech industry faces increasing pressure to develop more environmentally friendly alternatives to conventional electronics. Traditional memristors and semiconductors often require costly rare-earth minerals and consume substantial energy in data centers.
Meanwhile, mushroom-based systems offer a radically different approach. “Society has become increasingly aware of the need to protect our environment,” co-author Qudsia Tahmina reportedly observed. The natural resilience and unique electrical properties of mushrooms make them ideal candidates for what researchers call bioelectronics.
Building on this flexibility opens up numerous applications. Analysts suggest larger mushroom systems could prove useful in edge computing and aerospace exploration, while smaller implementations might enhance autonomous systems and wearable devices.
From Lab to Reality
While organic memristors remain in early development, the pathway to practical implementation appears surprisingly accessible. “Everything you’d need to start exploring fungi and computing could be as small as a compost heap and some homemade electronics,” LaRocco noted, suggesting that both small-scale and industrial production are viable with current resources.
The research team at Ohio State University acknowledges that future work will need to focus on improving cultivation techniques and dramatically miniaturizing the devices. Viable fungal memristors would need to be far smaller than what researchers achieved in this initial work.
Still, the implications are substantial. As computing continues to evolve beyond traditional silicon, nature-inspired solutions like mushroom-based memory could represent the next frontier in sustainable technology—proving that sometimes the most advanced solutions grow right beneath our feet.
