Abstract :
Comparative study of CMOS SRAM 8 K for different SOI structures (SIMOX, Smart-Cut and Dele-Cut) and SOS structures has been carried out. Radiation tests have been provided using laser and x-ray simulators in order to estimate CMOS SRAM stability to radiation pulse and total radiation dose. The tests have been carried out in active mode. The level of information safety for SRAM samples on SOI structures was three times higher than that for the samples on SOS structures. Research of the influence of total radiation dose has shown that the level was of 6middot104 units for SOS and SOI structures.
