TimeKeeper SRAM and ZeroPower SRAM are non-volatile static rams that have a 10 year retention. Those that I have seen and have in mind are dip chips and are not compatible with simms. There is one company that specializes in zeropower srams, so I will check back to give info about simm compatible ones once I refind the company. Try going around the use of simms and use dips.
How much memory allocation do you want? Zeropower chips prices start to rocket after 8kX8. Battery backed static ram is a good idea for personal use. STrams have a handy chip disable control for low power backup mode. Again, memory size about 512KX8 starts to climb in price.
