Abstract
Mono-energetic beams and full spectrum beams have been used for years to calculate the soft error rates of SRAM devices. Each beam type offers advantages and disadvantages, but availability is one of the major issues with full spectrum beams due to limited number of facilities available worldwide. We present correlation data for the newly made available full spectrum ANITA (Atmospheric-like Neutrons from thIck TArget) neutron beam at TSL, Sweden and the corresponding mono-energetic neutron beam. Single bit and multi bit events on a 90 nm SRAM ldquogolden devicerdquo are correlated and compared. In addition we also compare the soft error rates to a single 180 MeV neutron beam run to further investigate the accuracy of this method. The soft error rates extracted from the different methodologies are comparable and allow the use of the full spectrum ANITA beam for modern SRAM devices.
