SEU measurements and predictions on MPTB for a large energetic solar particle event

Single-event upset (SEU) ground testing and rate calculations have been performed for 16-Mb DRAMs flown on the microelectronics and photonics testbed experiment (MPTB) using measured particle spectra and compared with space data from a period of high solar activity. The results show that with the measured spectra, the measurements agree quite well with the calculations. Using just modeled environments, the results do not agree as well.
