Abstract
In this study, we have developed a SiGe dot floating-gate flash memory with high-K dielectric (HfO/sub 2/) tunneling oxide. Using SiGe dots and HfO/sub 2/ tunneling oxide, a low program/erase voltage can be achieved, along with good endurance and charge retention characteristics as compared to the SiGe dots with a SiO/sub 2/ tunneling oxide. We have also examined the impact of Ge concentration in the SiGe dots on charge retention time. This demonstrates that the SiGe dots with HfO/sub 2/ tunneling oxide can be used as the floating gate to replace SiGe dots with SiO/sub 2/ tunneling oxide and have a high potential for further scaling of floating gate memory devices.
