Patent number: 10861547Abstract: In some embodiments, the present disclosure relates to a method of operation a resistive random access memory (RRAM) cell, comprising the performing of a reset operation to the RRAM cell. A first voltage bias is applied to the RRAM cell. The first voltage bias has a first polarity. The application of the first voltage bias induces the RRAM cell to change from a low resistance to an intermediate resistance. The intermediate resistance is greater than the low resistance. A second voltage bias is then applied to the RRAM cell. The second voltage bias has a second polarity that is opposite to the first polarity. The application of the second voltage bias induces the RRAM cell to have a high resistance. The high resistance is greater than the intermediate resistance.Type: GrantFiled: May 21, 2019Date of Patent: December 8, 2020Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Chao-Yang Chen, Cheng-Jun Wu, Chun-Yang Tsai, Kuo-Ching Huang
