Testing Methodologies and Results of Radiation Induced Soft Errors for a COTS SRAM, FRAM, and SoC

Methods for testing commercial off-the-shelf (COTS) digital devices at varying levels of complexity is presented and discussed as well as the results for testing a COTS SRAM, FRAM, and SoC using these methodologies in a pulsed dose rate environment at Little Mountain Test Facility (LMTF) and neutron testing at Los Alamos Neutron Science Center (LANSCE). Investigations at LMTF revealed a dependence in all three devices on the integrated dose of a single pulse of radiation, implying that the duration of radiation plays a significant role in the response. The test infrastructure necessary to dynamically access an FRAM at LMTF and time the access with the pulse of radiation allowed for the discovery of a new FRAM failure mode where an entire word of the FRAM becomes corrupted as well as selecting between two different failure modes based on the timing of the pulse. A novel component-based testing methodology for testing complicated SoCs is presented and used to report on the cross-sections of several components on the Xilinx MPSoC, including its DMA which has not previously been reported.
