Recently the importance of cosmic ray neutron-induced soft errors has been
recognized. We propose a simple model to estimate the neutron-induced soft
error rates (SER's), which is a modified version of the burst generation ra
te (BGR) model. Our model can he used to easily and quickly estimate neutro
n-induced soft error rates and provides a useful guideline for device and c
ircuit engineers to estimate neutron-induced soft errors (SE's).
