Experimental evidences are presented showing obvious differences in threshold ion range for silicon-on-insulator (SOI) and bulk static random access memories (SRAMs). Single event upset (SEU) cross sections of SOI SRAMs start to decline off the Weibull curve at ranges 20.7 μm 40.6 μm, depending on species also thickness metallization layers. Whereas SRAMs, Bismuth beam is unexpectedly larger than 60.4 μm. Underlying mechanisms further revealed by Monte Carlo simulations in-depth analysis....
We investigate the impact of heavy ion irradiation on a hypothetical static random access memory (SRAM) device. Influences angle, critical charge, drain-drain spacing, and dimension device structure sensitivity have been studied. These prediction simulated results are interpreted with MUFPSA, Monte Carlo code based Geant4. The show that orientation beams different charge exert indispensable effects multiple-bit upsets (MBUs), decrease in spacing distance between adjacent cells or cells, is...
The dependence of single event upset (SEU) on heavy ion energy was investigated for partially depleted silicon-on-insulator static random access memories.

Ion species dependence energy-loss are also investigated. For given beam, results...
The influence of the metric linear energy transfer (LET) on single event upset (SEU), particularly multiple bit (MBU) in a hypothetical 90-nm static random access memory (SRAM) is explored. To explain odd point higher LET incident ion but induced lower cross section curve SEU section, MBUs by ions 132Xe and 209Bi with same different energies at oblique incidence are investigated using multi-functional package for effect analysis (MUFPSA). In addition, comprehensive analytical model radial...

The effects of temperature on the single-event upset (SEU) response commercial and radiation-hardened SRAMs are investigated by experiment. results showed that SEU sensitivity relied during testing.
