In a similar vein, why can we not use the technology of RAM to prolong the life-cycle of an SSD?

At least on older x86 motherboards, there used to be a dram refresh interrupt. It would trigger every 15 or so milliseconds and tell the dram controller to do a bus hold request and then refresh the ram. This bus hold request means the cpu can't access the ram when this happens (it can still run stuff in the cache) but at least you aren't wasting as much cpu time on dram refresh this way.
