I've been curious how a USB flash drive stores the memory without a power source? For example a GBA game stores is using a CMOS battery of some sort (only saying CMOS cause they look exactly the same and the same size battery) so yeah I've been curious how a flash drive keeps its memory without a power source?
Thanks for your help

it cant hold the information without a power source so what about when its not connected to the power
such as a motherboards CMOS settings needs a CMOS battery to store it while the computer is off
as for a hard drive makes engravings into the disc letting it store the information without needing a power source
so my question is how does it keep the information when its not connected to the computer cause i know USB drives don't have a Battery of any sort an i know it doesn't make engravings cause its all chips
Please someone who actually knows how this works answer my Question instead of saying it has a power source (the computer) because that takes away the whole point
 
May I answer your question with another question ? :?

A BIOS chip, it stores information as well, but when you remove the battery in a motherboard then it resets but how does it still have the information like which options to give in the BIOS options?

A bios is basically also a type of flash disk, but is only able to get written to by flashing it. I'm not too sure how exactly it stores the info but if you ask me i'd think that it integrates it into the chip. So what i am trying to say is that its not only a flash disk that works like that.

Some info that might help you is to check Wiki for the difference between a Disc and a Disk. Oh yea, BIOS = Basic Input Output System.
