JEDEC JESD89A

This specification defines the standard requirements and procedures for terrestrial soft-error-rate (SER)testing of integrated circuits and reporting of results. Both real-time (unaccelerated) and acceleratedtesting procedures are described. At terrestrial, Earth-based altitudes, the predominant sources of radiation include both cosmic-ray radiation and alpha-particle radiation from radioisotopic impurities in the package and chip materials. An overall assessment of a device¿¿s SER is complete, only when an unaccelerated test is done, or accelerated SER data for the alpha-particle component and the cosmic-radiation component has been obtained.
