In theory, just getting current does nothing. It has to be rewritten. It uses hot electron tunneling.
However, I recently found an mp3-player I hadn’t used since longer than 2017 on the bottom of a drawer. It was stored without battery. I put an AAA battery in and it played the stored music just fine.
Older devices also stored fewer bits per well. It’s much easier for the data to get corrupted when the difference in voltage between two values is smaller.

Older lithography holds charge longer; the pursuit of more storage at cheaper prices results in engineering sacrifices to make it happen.
