Abstract
- Single and multiple-event upsets in \ HfO_2/\ Hf one transistor, one resistor (1T1R) resistive random access memory (RRAM) structures are modeled dynamically using 3-D technology computer-aided design (TCAD) simulations. A dynamic single-event compact model is presented that allows direct correlation of the ion-generated voltage transient across the RRAM and the change in RRAM resistance. Experiments and modeling demonstrate an exponential relationship between the susceptibility of the RRAM and the applied voltage. Two implementations of the model are also presented including hardening voltage-susceptible resistive memory technologies and the impact of highly scaled access transistors. [ABSTRACT FROM PUBLISHER]
