Yes, it is true.  If you have 4GB of RAM, you need at least 4GB in order
to hibernate and suspend to disk.

All the contents of RAM are written to swap and that is used to come
back up in the "saved" state.  This is also why, if you have encrypted
partitions, you need to have encrypted swap as well.

What I am confused about are the two names used to suspend:  the mode
where you use zero power and everything is written to disk and the mode
where you just shutdown the drives, screen, and only use RAM.
