Resistive-switching behavior in Ti/Si3N4/Ti memory structures for ReRAM applications
In this paper, the resistive-switching behavior of Si3N4 films using nitride-related traps in Ti/Si3N4/Ti memory cells is reported. Bipolar resistive switching behavior was clearly observed at a low voltage of about 2.5V. Compared to Au/Si3N4/Ti memory cells, the set and reset current of Ti/Si3N4/Ti memory cells was decreased from 5?A and 1.5mA to 40nA and 1?A, respectively, at Vread=0.1V. In addition, Ti/Si3N4/Ti memory cells showed improved endurance characteristics over 2.7103 cycles.
