SRAM testing under Neutron Radiation for the evaluation of different algorithms stress

Abstract : Electronic system reliability over soft errors is very critical as the transistor size shrinks. Many recent works have defined the device error rate under radiation for SRAMs in hold mode (static) and during operation (dynamic). This paper evaluates the impact of running test algorithms on SRAMs exposed to neutron radiation, in order to define their stressing factor. The results that we show are based on experiments performed at the TSL facilities in Uppsala, Sweden using a Quasi-Monoenergetic neutron beam. The evaluation of the test algorithms is based on the calculated device SEU cross section.
