Abstract :
Heavy ions experiments are carried out on commercial 90 nm and 65 nm SRAMs. The contribution of single and multiple cell upsets (MCUs) are discussed as a function of the LET for different memory cell areas and for triple well usage. Once again, well engineering plays a key role on MCU and SEE response of SRAM. Full 3-D TCAD simulations investigate the occurrence of parasitic bipolar effect.
