Abstract
The SEU hardness of a new CMOS storage cell based on latch redundancy has been analyzed using a laser beam simulation. We detected and investigated topology-dependent upset mechanisms due to charge collection at two sensitive nodes using a laser excitation between the nodes. Compact upset-immune device topologies are proposed, using spacing and isolation techniques for simultaneously sensitive node pairs, to achieve high immunity levels required in critical applications
