Penn State Team Fuses Synthetic DNA With Perovskite to Build Ultra-Low-Power Memory Device

A research team at Penn State has built a working memory device by coupling synthetic DNA with a perovskite semiconductor, a combination that has not been tried in this configuration before. The work, reported this week in Advanced Functional Materials, lands at a moment when the energy cost of data storage is a genuine engineering problem, not a hypothetical one.

The basic architecture is straightforward to describe, though harder to execute. <cite index="23-1,23-2,23-3">The approach relies on two main components: synthetic DNA made from chemically engineered short sequences designed for specific electronic functions, and crystalline perovskite, a semiconductor already used in solar cells, lasers, and data storage devices.</cite>

What makes this a memristor, rather than ordinary memory, is that it can store and process information in the same physical location. <cite index="20-3,20-4">Researchers combined synthetic DNA with a semiconductor to create an ultra-low-power memory device capable of storing and processing information in the same place, with the bio-hybrid technology potentially making AI systems and next-generation computers far more energy efficient.</cite>

The motivation for reaching toward biology is partly about density. <cite index="20-6,20-7">DNA serves as the genetic blueprint for every living organism, but it's also an extraordinarily dense way to store information, with a single gram capable of holding about 215 million gigabytes of data.</cite> The problem, until now, has been integration. <cite index="20-9">The challenge has been finding a way to make biological DNA function effectively alongside electronic materials.</cite>

Co-corresponding author Kavya S. Keremane, a postdoctoral researcher in materials science and engineering at Penn State, framed the core difficulty in remarks reported by SciTechDaily: <cite index="23-4,23-5">"Biology and electronics are different domains," she said, and "bridging these two fields required developing an entirely new materials platform that allows them to function seamlessly together."</cite>

The ScienceDaily write-up, citing Penn State, reports that the device uses approximately 100 times less power than existing memory technologies, though the release does not specify the direct comparison benchmark. That detail matters: 'less power than' claims in materials science often depend heavily on which baseline you choose, and readers should look at the supplementary data in the paper itself before treating the round-number figure as settled.

The underlying paper, authored by Keremane and colleagues including senior authors Shashank Priya and Bed Poudel, was supported by the U.S. National Science Foundation and the National Institutes of Health, with additional support from Penn State and the University of Minnesota. <cite index="23-1">A patent application is underway.</cite>

Context worth keeping in mind: perovskites have a well-documented stability problem. They degrade under humidity and heat, which has complicated their commercial use in solar cells for years. The paper's title, which includes the phrase "highly stable memristors," suggests the team addressed this directly, but independent replication of stability claims under real operating conditions is the next bar the work needs to clear.

<cite index="20-8">Bringing DNA's storage capacity into electronics could lead to more efficient data centers, faster processing, and systems capable of handling increasingly complex information</cite>, the researchers argue. That's a reasonable long-term framing. How far from bench to manufacturable device this particular architecture sits is a question the paper alone cannot answer.

The study was published January 19, 2026, in Advanced Functional Materials and picked up wider attention this week after ScienceDaily covered it on August 17.
