Abstract :
This paper presents the SEU & MCU detected by several dedicated memories of the instrument ICARE (on-board the Argentinean satellite SAC-C) from November 2000 to May 2009. The correlation between SEU rate and the space environment is shown along with the evolution of the geomagnetic cutoff, the geographical dependence of the MBU multiplicity inside the SAA is also shown. Moreover, the output of MUSCA SEP3 (SEE prediction code) has been compared with in-flight data obtaining a good match.
