Why do SSDs have a more limited number of times data can be written to them, but RAM memory can handle loads of re-writes? (lemmy.world)

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

SSDs typically use flash memory, as I understand it. I'd leave the sand out and say it's like a tank you fill up with (more or less depending on the data) water. After a while the tank mechanically wears out and starts to leak. Flash memory very much is like a tank filled with electricity and then plugged, and it does start to leak as the insulating oxides degrade.
