Abstract :
This research predicts the effects of the natural radiation environment in low earth orbit on a 6T SRAM cell designed using the CMOS portion of a 130 nm BiCMOS technology. It is determined that this technology is quite sensitive to single event upset (SEU): at 200 km altitude and without shielding, the predicted SEU rate is 6.7×10-3 bit-1yr-1; at 2000 km altitude, the rate increases to 1.9×101 bit-1yr-1. Nonetheless, these results compare favorably to previously published SEU data [1], [2] regarding the bipolar portion of similar BiCMOS technology.
