If both USB memsticks and SSD disks use the same technology, why does only the latter “forget” data?

I recently learned (or was tricked into believing) that SSD disks actually forget all their data on them if left unpowered for just a year.

Assuming that this is true, and I’ve spent more than enough time trying to debunk it, how then can my USB memsticks, memory cards in my EverDrives and even my Sony PlayStation memory card from the 1990s still hold data while being powered on once every few years?

Nothing that’s claimed online seems to ever actually be the case. SSDs must be using some other technology which has much faster performance but at the price of nonexistent archival value?

I wish there were a clear, correct table showing all current storage media technologies and how long they last while powered off and other data like that. It’s impossible to find, like everything else I search for.
