Yes you can encrypt and/or compress RAM, but of
course you get lower performance. Extreme case
would be encrypting all pages apart from the one
you are using, automatically, hand having a task
which re-encrypts all pages as soon as you no
longer touch them for a short time. For important
data such as keyrings, it is certainly worth the
effort to encrypt it in RAM and only decrypt it at
the moment when you actually have to work with the
real data...

What is FDE?

If things were like that, you could not encrypt disk, either.

Not if you use encryption, then you only have to hide keys.
