Comparison of NMOS and PMOS transistor sensitivity to SEU in SRAMs by device simulation

The off-NMOS and off-PMOS transistor single-event upset (SEU) sensitivities are studied in a 0.6-[micro]m SRAM. In some cases, the off-PMOS sensitivity is shown to be similar to the off-NMOS one. This could affect SEU rate calculations. Index Terms--Electric field, NMOS, PMOS, SEU, SRAM, transistor sensitivity.
