Call your MOSTEK sales rep and ask for their "zeropower rams".
They come in standard 2K X 8 and 8K X 8 packages with built in long life
lithium cells.

I have used a version that is a 2K X 8 chip with the last 8 bytes dedicated
to a built in real-time clock.  It has worked flawlessly for several years
and the battery is only drained when the power is off.  They offer a special
low power mode for storage.

I think one of the part numbers is MK48T02, I may be wrong on that one.
