Abstract

Heavy ion single-event measurements and total ionizing dose (TID) response for 8Gb commercial NAND flash memories are reported. Radiation results of multilevel flash technology are compared with results from single-level flash technology. The single-level devices are less sensitive to single event upsets (SEUs) than multi-level devices. In general, these commercial high density memories exhibit less TID degradation compared to older generations of flash memories. The charge pump in this study survived up to 600 krads.
