In this work, three different RRAM compact models implemented in Verilog-A are analyzed and evaluated in order to reproduce the multilevel approach based on the switching capability of experimental devices. These models are integrated in 1T-1R cells to control their analog behavior by means of the compliance current imposed by the NMOS select transistor. Four different resistance levels are simulated and assessed with experimental verification to account for their multilevel capability. Further, an Artificial Neural Network study is carried out to evaluate in a real scenario the viability of the multilevel approach under study. 2021-04-27T09:56:30Z 2021-04-27T09:56:30Z 2021-03-11 journal article Pérez-Bosch Quesada, E.; Romero-Zaliz, R.; Perez, E.; Kalishettyhalli Mahadevaiah, M.; Reuben, J.; Schubert, M.A., Jimenez-Molinos, F., Roldan, J.B.; Wenger, C.
