Abstract :
Heavy ion single-event measurements and total ionizing dose (TID) response for 8 Gb commercial NAND flash memories are reported. Radiation results of multi-level 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.
