Abstract: The total dose radiation response of two classes of floating gate nonvolatile memory devices is examined. While the hardness of commonly studied double polysilicon cells is restricted to a few kilorads, devices having only one polysilicon layer are shown to be much more radiation-hard. This is mainly due to the thinner oxide that can be used in the coupling capacitor of such cells. It is also shown that the contribution of the field oxide regions, present under the floating gate of the cells, is of major importance for their radiation response. Finally, the programming behaviour of the devices is shown to remain fairly unaffected by the ionizing radiation.
