Abstract

In this paper, the resistive-switching behavior of Si 3N 4 films using nitride-related traps in Ti/Si 3N 4/Ti memory cells is reported. Bipolar resistive switching behavior was clearly observed at a low voltage of about ±2.5 V. Compared to Au/Si 3N 4/Ti memory cells, the set and reset current of Ti/Si 3N 4/Ti memory cells was decreased from 5 μA and 1.5 mA to 40 nA and 1 μA, respectively, at V read = 0.1 V. In addition, Ti/Si 3N 4/Ti memory cells showed improved endurance characteristics over 2.7 × 10 3 cycles.
