Do you have more info?
The minimum specs I've seen for NAND flash chips are 10 year retention time at room temperature.
Being powered on isn't enough to change this, the firmware would have to be actively reading, erasing and writing blocks of data to refresh them. I'm sure there are some that will do this, but it would increases some other data loss risks, wear rates and power draw; so I suspect (?) it's not universal.
My professor told me this fact in class, but upon searching for papers I did not find anything to support it.
So probably you are right.
Me having some datasheets that claim one thing doesn't mean it applies to everything and every implementation. Your prof might be right.
