  • Abstract
    At 150degC under a fast 100 mus and low plusmn9 V P/E voltage, the [TaN-Ir3Si]-HfAlO-LaAlO3-Hf0.3O0.5N0.2-HfAlO-SiO2-Si memory device shows good device integrity of a 3.2 V initial DeltaVth and 2.4 V 10-year extrapolated retention. This only 25% retention decay at 150degC was achieved by double quantum barriers confining trapped carriers in deep Hf0.3O0.5N0.2 well.
