For a new design I'm thinking of using FRAM instead of the SRAM for data
storage in a redesign of one of in our products.
The FRAM looks good in terms of its non-volatility (10 yrs) and is available
with serial or parallel interfaces, speed is acceptable - we don't need
"fast".
At work we're using a the Simtek STK17TA8 that looks like an SRAM, but
when it loses power it does an "autostore[tm]" using power it saved on
a special Vcap (under 100uF) pin. It's also a realtime clock which can
be battery or supercap backed.
