Maybe this is out of PIC discussion range, but I have used SIMTEK STK12C88 (
32*8 nvSRAM)  ( 28pins DIL).
It is like SRAM, but it has EEPROM mirror. RAM is moved to permanent ( =
nonvolatile) part by store and read commands under sowtware calls.
I have tried these in my 8051-project.

I have not visited in their homeplace http://www.csn.net/simtek or
or http://simtek.com/simtek/docs/ProductList.html. I do not got any
responces from these addresses somehow.

They also have hardware Autostore-products ie.after power down they
automatically store RAM to EEPROM. They need 100uF power capacitor and tree
resistors to detect power down. They promiced to deliver first 32k*8
autostore device for me for christmas. Let's see..
