Reduction of charge-transport characteristics of SiGe dot floating gate memory device with ZrO2 tunneling oxide.

Reduction of charge-transport characteristics of SiGe dot floating gate memory device with ZrO2 tunneling oxide.

We have demonstrated the effects of charging voltage and the charge retention characteristics in silicon-germanium dots with ZrO2 tunneling oxide. Using the ZrO2 high-k dielectric tunneling oxide, we achieved a low write voltage and improved retention time as compared to the SiGe dots with a SiO2 t...
