Penn State fuses synthetic DNA with perovskite into a memory device using 100x less power

Penn State researchers combined chemically synthesized short DNA strands with a perovskite semiconductor to build a "bio-hybrid" memory device that stores and processes information in the same place, using roughly 100x less power than conventional chips. The paper appeared in Advanced Functional Materials and a patent has been filed.

Why it matters

Today's AI data centers separate memory from processing, and shuttling data between them burns enormous energy; this device eliminates that gap.
Density: one gram of DNA can hold 215 million GB — the entire internet (100 EB) would fit in a few kilograms, far beyond silicon.
The team used engineered synthetic DNA (not biological), fused with perovskite, a semiconductor already used in solar panels. Co-lead postdoc Kavya Keremane noted that bridging biology and electronics required an entirely new materials platform.

The author argues AI's energy problem is accelerating and the 60-year hardware roadmap is hitting physical limits; next-gen AI needs a radically different substrate or faces a hard ceiling. The work is early, but it's the first time DNA and a mainstream semiconductor have functioned together in a working memory device.
