Penn State researchers build DNA-based computer memory device

• Researchers combined synthetic DNA with perovskite material and silver nanoparticles to create a memristor, a type of electronic component that can store data.
• The device stores information in very small physical spaces while using minimal power, potentially making computer memory systems more compact and efficient.
• The technology could eventually support AI systems and brain-inspired computing applications that require less energy than current approaches.
