高密低耗“生物—电子”存储设备研发成功

Core Insights - A research team from Pennsylvania State University has developed a novel "bio-electronic" storage device by combining synthetic DNA with semiconductor material perovskite, achieving higher storage density and power consumption only one percent of traditional storage devices [1][2]. Group 1: Technology and Innovation - The new storage device leverages DNA's immense information storage capacity, which can store up to 215 million GB of data per gram, potentially leading to more energy-efficient data centers and powerful computing devices [1]. - The breakthrough involves embedding silver nanoparticles into a carefully designed synthetic DNA chain and integrating it with a perovskite film, allowing for precise control of material properties and enabling DNA to gain conductivity [1][2]. - The device operates as a "memristor," capable of retaining information even when power is cut off, mimicking the functionality of human neurons and paving the way for more efficient and intelligent "brain-like computing" [2]. Group 2: Performance and Stability - Testing results indicate that the doped DNA and perovskite form a unique "bio-electronic hybrid channel," allowing stable electron flow at voltages below 0.1 volts, with rapid response to current direction changes [2]. - The device can operate stably at room temperature for over six weeks, significantly outperforming similar perovskite storage devices, while maintaining a storage density that exceeds traditional options [2]. Group 3: Future Implications - The research highlights the potential for integrating biological materials with semiconductors, suggesting a shift from traditional silicon-based storage and processing units to bio-inspired designs that enhance efficiency and intelligence at the nanoscale [3]. - As artificial intelligence demands for computational power and energy efficiency rise, such low-power, high-performance devices will become increasingly critical [2].
