Resistive switching memory devices based on organic materials are intriguing. These devices are biodegradable and nontoxic to living organisms. In this work, using euphorbia cotinifolia plant extract was investigated for its applicability as an active layer of a resistive switching memory device consisting of silver top electrode and indium-doped tin oxide bottom electrode. This study selected Euphorbia cotinifolia because it is a common, prolific and simple-to-grow plant in many South African homes. When the euphorbia cotinifolia plant is broken, an extract resembling milk is emitted. This extract was collected directly onto the bottom electrode, which was then dried at ambient temperature. For top electrode, silver paste was applied. The entire fabrication process was devoid of heat and electricity. The fabricated device showed impressive properties such as memory hysteresis with $\mathrm{\text{ON/OFF}}=5$, endurance of over $32$ write/erase cycles, and an impressive retention of $\ge 10^3\mathrm{\text{s}}$. Therefore, this system may be a candidate for a nonvolatile and disposable memory device.

基于有机材料的电阻开关存储器件很有趣。这些装置可生物降解，对生物体无毒。在这项工作中，研究了大戟植物提取物作为由银顶电极和掺铟氧化锡底电极组成的阻变存储器件有源层的适用性。这项研究选择了大戟，因为它是许多南非家庭常见、多产且易于种植的植物。当大戟植物被折断时，会释放出类似牛奶的提取物。该提取物直接收集到底部电极上，然后在环境温度下干燥。对于顶部电极，施加银浆。整个制造过程没有热量和电力。所制造的器件显示出令人印象深刻的特性，例如记忆滞后$\mathrm{\text{开关}}=5$, 耐力超过$32$写/擦除周期，以及令人印象深刻的保留$\ge 10^3\mathrm{\text{s}}$。因此，该系统可以是非易失性和一次性存储设备的候选者。
