Continued testing 1130MRAM board - retrigger problem continues to bedevil me

STRONG FILTERING ON INPUT DID NOT STOP THE RETRIGGER

I upped the RC network to a much longer time constant to see if that would block a short duration glitch on the input. The image below shows the incoming +Storage Read signal in yellow and the output of my filter in green. Purple is the output of the NAND gate. Blue is an unrelated signal. 

The rising edge of the 1130 control signal is smoothed out and has a slow slope, so that the NAND gate doesn't trigger until about 450 nanoseconds after the actual signal rising edge arrived in yellow. However, the short duration noise in yellow would definitely be absorbed yet we see stronger noise after my filter. 

FOCUS NEEDS TO BE TOTALLY ON MY BOARD

I am convinced that the problems are not coming from the 1130 signal +Storage Read nor any issue such as lack of termination or induction on the cables. They are generated on my board. I will keep plugging away at this until I figure out the problem and resolve it. I believe the board will work well once I get this side issue fixed.
