UPS fuel cell based: An innovative back-up system
2007
The aim of the paper is to evaluate the technical feasibility and aspects related to the use, in an Uninterruptible Power Supply (UPS), of fuel cells instead of traditional electrochemical batteries. The proposed system, named UPS-FCB (Fuel Cell Based) presents a modular and versatile system configuration; particularly it is possible to integrate it with traditional UPS. Moreover the system features can be modified in terms of power, reliability, back-up time, etc., by changing the power devices. A detailed experimental analysis has been carried out on a passive stand-by UPS integrated with a FCB; experimental results can be easily extended to the other possible system architectures. © 2007…
Comparison of TID response and SEE characterization of single- and multi-level high density NAND flash memories
2009
Heavy ion single-event measurements and total ionizing dose (TID) response for 8Gb commercial NAND flash memories are reported. Radiation results of multilevel flash technology are compared with results from single-level flash technology. The single-level devices are less sensitive to single event upsets (SEUs) than multi-level devices. In general, these commercial high density memories exhibit less TID degradation compared to older generations of flash memories. The charge pump in this study survived up to 600 krads.

$\Upsilon$(2S) $R_{\rm pPb}$ values at $\sqrt{s_{\rm NN}}$ = 8.16 TeV. The first uncertainty is statistical, the second is the uncorrelated systematic, while the third one is a correlated systematic uncertainty.
Heavy-Ion Radiation Impact on a 4 Mb FRAM Under Different Test Modes and Conditions
2016
International audience; The impact of heavy-ions on commercial Ferroelectric Memories (FRAMs) is analyzed. The influence of dynamic and static test modes as well as several stimuli on the error rate of this memory is investigated. Static test results show that the memory is prone to temporary effects occurring in the peripheral circuitry, with a possible effect due to fluence. Dynamic tests results show a high sensitivity of this memory to switching activity of this peripheral circuitry.
