Abstract :
Results of neutron induced single event upset (SEU) testing of two Synchronous Burst Static Random Access Memory (SRAM) devices, the Galvantech GVT71128G36 128K x 36 and the GSI GS816273CC 256K x 72, and the internal RAM (iRAM) in the Texas Instruments SM32C6713BGDPA20EP Digital Signal Processor (DSP) are described. Four samples of each device type were irradiated with a 14-MeV neutron source, with and without a polyethylene moderator. The units were irradiated using a continual read/write correct loop using several bit patterns. All units-under-test were operated during irradiation using the respective operating datasheet supply potential. It is noted that one of these devices exhibited a large low energy (<; 1MeV) neutron cross section.
