Abstract :
This paper presents the formation of CeO2 nanocrystals on SiO2 tunneling layer and its annealing effect to the nonvolatile memory device. The characteristics including the program/erase behaviors, data retention, and endurance of Silicon-Oxide-Nitride-Oxide-Silicon type memories embedded with cerium oxide (CeO2) nanocrystals were studied to demonstrate its advantages as a nonvolatile memory device.
