= Can a floating bus create enough noise inside a memory device
= to give rise to a soft error?

The place I've seen this cause a problem is when the floating bus is
connected to the input of a buffer. The buffer output will make many
transitions as the floating signal goes through the switching
threshold. I've seen this cause problems with memory systems on
several occasions, but usually when the buffer is driving the memory
data bus and the buffer input is floating.
