Abstract

Highly uniform current distributions of high resistance state (HRS) and low resistance state (LRS), low 0.6 pJ switching energy, fast 30 ns switching speed, and good 10 ⁶ cycling endurance are achieved in Ni/GeO _x/Ta ₂O _5-yN _y/TaN resistive random access memory (RRAM) devices. Such good performance is attributed to nitrogen-related acceptor level in Ta ₂O _5- _yN _y for better hopping conduction, which leads to forming-free resistive switching and low self-compliance switching currents.
