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?

RAM needs a current to keep it's data, if there is no power it will forget very fast. The SSD won't forget anything if power fails.

To save re-writes you would have to have data that only resides in the RAM memory part of the SSD, which, again, is delicate. Also SSDs basically have this, a bit of more durable flash memory which acts as a write back cache.
