Organic-resistance random access memory has high application potential in the field of next-generation green nonvolatile memory. Because of their biocompatibility and environmental friendliness, natural biomaterials are suitable for the fabrication of biodegradable and physically transient resistive switching memory devices. A flexible memory device with physically transient properties was fabricated with silver ions and egg albumen composites as active layers, which exhibited characteristics of write-once-read-many-times (WORM), and the incorporation of silver ions improved the ON/OFF current ratio of the device. The device can not only complete the logical operations of "AND gate" and "OR gate", but its active layer film can also be dissolved in deionized water, indicating that it has the characteristics of physical transients. This biocompatible memory device is a strong candidate for a memory element for the construction of transient electronic systems.
有机电阻式随机存取存储器在下一代绿色非易失性存储器领域具有很高的应用潜力。天然生物材料因其生物相容性和环境友好性，适用于制造可生物降解和物理瞬态的电阻式开关存储器件。以银离子和蛋清复合材料为活性层制备了具有物理瞬态特性的柔性存储器件，该器件表现出一次写入多次读取（WORM）的特性，银离子的引入提高了器件的开/关电流比。该器件不仅能完成“与门”和“或门”的逻辑运算，其活性层薄膜还能溶解于去离子水中，表明它具有物理瞬态特性。这种生物相容性存储器件是构建瞬态电子系统的存储元件的有力候选者。
