Abstract :
This work reports the combined characterization at mountain altitude (on the ASTEP Platform at 2552 m) and at sea-level of more than ~50 Gbit of 90 nm NOR flash memories subjected to natural radiation (atmospheric neutrons). This wafer-level experiment evidences a limited impact of the terrestrial radiation at ground level on the memory SER evaluated without ECC. Experimental values are compared to estimations obtained from Monte Carlo simulation using the TIARA-G4 code combined with a physical model for charge loss in such floating-gate devices.
