摘要

来自清华大学、北京英诺迈科技有限公司和北京微电子技术研究所的研究人员通过对器件、电路和操作层面的优化，将续航时间提高到了107次。在器件层面，该团队在基于氧化铪（HfOx）的电阻开关层和氧交换层之间引入了接口调制层。这调节了界面上的氧空位，并将它们限制在细丝周围的区域。退火步骤用于减少制造过程中在侧壁产生的氧空位，氧空位导致导电细丝的形成无法重置。这将有缺陷的比特从每4mb大约48个比特减少到零——测量的产率为100%。在电路层面，研究人员创造了一种联合限流方法来减少写入操作的问题，以及一种自适应操作电压方法，该方法根据单元地址自适应地调整顺应性和位线/源线电压，以降低形成环路的错误率。还实现了反向操作，以减少不稳定位的影响。在晶圆上随机选择位置嵌入三个RRAM 2kb细胞，在107次循环后，高电阻和低电阻状态没有重叠，并且在125°C下保持约12年。
