Abstract : Several non-radiation-hardened high density static RAMs (SRAMs) were tested for susceptibility to single-event upset (SEU) and (latchup). Test results indicated that at present only a few such device types are suitable for use in space applications. Several additional factors such as susceptibility to multiple-bit upsets and to radiation-induced permanent damage need to be taken into consideration before these device types can be recommended. One non-hardened SRAM device type has recently been used on a low-Earth orbit satellite, enabling the upset rate measured in space to be compared to that predicted from ground-based testing.
