Abstract
The authors evaluate tolerance to proton upset for three kinds of memories and one microprocessor unit for space use by irradiating them with high-energy protons up to nearly 70 MeV. They predict the error rates of these memories using a modified semi-empirical equation of W.L. Bendel and E.L. Petersen (1983). A two-parameter method was used instead of Bendel´s one-parameter method. There is a large difference between these two methods with regard to the fitted parameters. The calculation of upset rates in orbits were carried out using these parameters and NASA AP8MAC, AP8MIC. For the 93419 RAM the result of this calculation was compared with the in-orbit data taken on the MOS-1 spacecraft. A good agreement was found between the two sets of upset-rate data
