Any references? I tried to find something but I failed. I'm assuming we are talking about something different than UPS + going to sleep? It seems very tricky to just keep RAM powered.

Intel has a reference design for just keeping RAM powered but it's only used in storage controllers, not in any servers you can buy.

Check out Adaptec RAID controllers. Notice how these guys have an extra battery back so that during critical power failure the large (2GB?) cache is preserved.
