Abstract
A memory cell having a plurality of transistors connected so as to restore a data value to a node of the memory cell to an initial value following an event upsetting the initial value has an aspect ratio of at least 5:1. The high aspect ratio provides adequate spacing between nodes of the memory cell for SEU tolerance at small design technologies.
