Single Event Effects in COTS Ferroelectric RAM Technologies

Single event effects (SEE) in two commercial-off-the-shelf (COTS) Ferroelectric Random Access Memory (FeRAM) technologies were investigated by heavy ions and pulsed laser irradiation. At least six SEE types were observed. The majority of the errors were caused by anomalies in the peripheral circuit, which was confirmed by the mirror SRAM technique, non-volatile test mode, and the detailed error information. Single event upset, single event functional interrupt and single event latchup cross sections were reported, with weak dependence on the supply voltage.
