I just received some Ramtron FRAM chips (FM25040-P's) from Future
Electronics.  The chips are sealed in a de-aired plastic package along with
what appears to be a dessicant pouch.  And there is a warning that says:

"CAUTION This bag contains moisture sensitive devices"
It goes on to state that shelf life in the bag is 12 months at <40 degrees C
and <90% relative humidity (RH).  It then says that chips not immediately
mounted after removal from the bag must be baked and it has a schedule of
baking options.  There are no instructions suggesting what the life span of
chips are after mounting, which is curious, since merely soldering the leads
on the chip does not protect the chip from moisture.

Is this warning message:
A) the work of prankster
B) some paranoid label that gets put on all bags leaving Future Electronics
C) a real warning, in which case Ramtron is severely misrepresenting its
products.  Ramtron makes no mention of humidity sensitivity on the data
sheet for the chip.
