Patent number: 11696521Abstract: Various embodiments of the present disclosure are directed towards a memory cell comprising a high electron affinity dielectric layer at a bottom electrode. The high electron affinity dielectric layer is one of multiple different dielectric layers vertically stacked between the bottom electrode and a top electrode overlying the bottom electrode. Further, the high electrode electron affinity dielectric layer has a highest electron affinity amongst the multiple different dielectric layers and is closest to the bottom electrode. The different dielectric layers are different in terms of material systems and/or material compositions. It has been appreciated that by arranging the high electron affinity dielectric layer closest to the bottom electrode, the likelihood of the memory cell becoming stuck during cycling is reduced at least when the memory cell is RRAM. Hence, the likelihood of a hard reset/failure bit is reduced.Type: GrantFiled: July 27, 2020Date of Patent: July 4, 2023Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chao-Yang Chen, Chun-Yang Tsai, Kuo-Ching Huang, Wen-Ting Chu, Cheng-Jun Wu
