Abstract
A simple circuit of one negative edge triggered flip-flop is shown below.  This should increase the LET resistance of the memory element, when compared to an R-Cell in SX and SX-A technology.  For SX-S, this is a technique that can be used to increase the number of flip-flops available.  However, data indicates that an R-Cell was used, not the pair of C-Cells, which would give the user an implementation that did not have the expected SEU tolerance.
