High charge storage characteristics of CeO2 nanocrystals for novolatile memory applications

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 studieded to demonstrate its advantages as a nonvolatile memory device.
