Abstract :
The on-orbit data of single event phenomena were obtained for the CMOS static RAMs equipped in Engineering Test Satellite-V (ETS-V) in a geostationary orbit. The single event latchup and single event upset data were acquired for a period of about three years, and the effects of solar flares were observed. A comparison with the data (single event upset) of TTL SRAMs by Marine Observation Satellite-1 (MOS-1: a medium-altitude satellite) was also conducted. The Poisson distribution and the extreme-value theory (doubly exponential distribution) were adopted to analyze the data. From this analysis a decrease of the number of single events could be found during the solar maximum
