Resistive switching memory devices based on organic as well organic–inorganic hybrid materials are emerging viable candidates for post-Moore nonvolatile applications. In this article, we report a write-once-read-many (WORM) resistive device (Al/7HNO3C/ITO) coumarin derivative 7-hydroxy-N-octadecyl coumarin-3-carboxamide (7HNO3C). The yield, retention time, read endurance, and window of the designed were found to be 36.11%, 4 × 103 s, 1270 cycles, ∼102, respectively. ZnO nanoparticles...
Development of biocompatible and biodegradable information storage could be one the major strides toward advancement next-generation eco-friendly electronics. Locally available leaves Ipomoea carnea (IC) are employed to design a nonvolatile resistive memory device having configuration Au/IC/ITO.
