Even if it’s powered, RAM will lose its data on the order of a tenth of a second. RAM doesn’t just require power, it requires that your computer constantly read and rewrite it - so every 64ms your computer has to read every gigabyte of RAM and write it back.
Yes - it’s been the job of the DRAM controller for almost the entire history of computing. But that’s still a part of the computer and if it stops working then your RAM will go blank in a fraction of a second

Doesn’t the ram do that itself? Otherwise reading/writing all that data would waste tons of time for the CPU.
