A study has been conducted of radiation effects in test MOS transistors, manufactured using 90 nm techno-logy, when irradiated with gamma rays at a dose rate of P = 0,1 rad/s in the passive mode. For research, we used a method for analyzing changes in surface mobility in the channels of MOS transistors with n- and p-channels. Two stages of surface defect formation were observed both in the case of MOS transistors with an n-channel and in p-channel transistors.

Keywords: MOS transistor, n-channel, p-channel, gamma radiation, surface defect formation.

An experimental dependence of single event upset (SEU) number vs 14 MeV neutron fluence was obtained for static random access memory (RAM) with error detection and correction (EDAC) w/o scrubbing. A software model of RAM has been developed to analyze experimental data. SEU cross-section in RAM has been defined and the efficiency of EDAC has been estimated based on the results of simulation. The model application allows to estimate radiation sensitivity of RAM with EDAC.

Keywords: single event upsets, RAM, Hamming codes, 14 MeV neutrons.
