SET-induced soft-error rates (SERSET) in logic LSIs are estimated from SET pulse-widths measured in logic cells used in logic LSIs. The estimated rates are consistent with directly measured SERSETS for logic LSIs.

A scan flip-flop (FF) is designed to observe both single event transient (SET) and single event upset (SEU) soft errors in logic VLSI systems. The SET and SEU soft errors mean the upset caused by latching an SET pulse that originates in combinatio...

The memory reliability of magnetic tunnel junctions has been examined from the aspect of their potential use in disaster-resilient computing. This computing technology requires memories that can keep stored information intact even in power-cut eme...
This paper presents analysis results for the onorbit performance of a solar array paddle of the X-ray astronomy satellite Suzaku. The current generated by the solar array was decreasing significantly for approximate one year after mid-2011. We est...
