Impact of nanoscale polarization relaxation on endurance reliability of one-transistor hybrid memory using combined storage mechanisms

We demonstrate a novel hybrid nonvolatile memory integrated with a charge trapping mechanism and a ferroelectric polarization effect. The hybrid memory features a large threshold voltage window of 2V, fast 20-ns program/erase time, tight switching margin, and long 1012-cycling endurance at 85oC. Such excellent endurance reliability at 85°C can be ascribed to the introduction of charge-trapping node into the design of memory structure that not only weakens temperature-dependent polarization relaxation, but also improves high-temperature endurance reliability.
