FYI,
Ramtron was acquired by Cypress Semiconductor. I've had trouble finding
some FRAM parts, but that may be changing as Cypress scales up production.
Also, watch out for fraudulent parts on ebay. I've ended up buying a
couple things that were bad, although not ramtron parts.
Anyway, Keep us posted on the FRAM upgrade. I'm curious how it works out.

I'm looking at the A5 board in my 3458A.
The DS1220Y and the two DS1230Y NVRAMs have 1997 dates, so should likely be
replaced. I *think* the Ramtron FM1608-120-P is a direct "drop-in"
replacement in this application for the DS1230Y. Is that right? If so I'll
get some in from eBay.
Is there an FRAM direct replacement for the DS1220Y-150? Or should I use a
FM16W08 on a 28 way SOIC to DIP adapter as per
