Pray tell, how does RAM manage to retain data when the power is off? 
It's either six transistors or one transistor and a cap per cell = not 
persistent.

I don't know of any magic persistent RAM that's fast enough for use as 
main RAM. Flash disks are of course another story but you do appear to 
be talking about system RAM
