Interesting stuff.  I just found references in Partminer at around the
$1.60 range for 2K Byte FRAM.  This is very close to what I want.  I have a
slight concern about the 10 Giga write lifetime as I will be hitting my
memory pretty frequently and pretty hard.  Ideally for me I'd like
something like this (SPI two wire bus) but with RAM instead of the
non-volatility.  This is a very cool p[roduct that I will probably use for
other stuff sooner or later.

Thanks for the pointer.
