Flash memories are well known
you can check here if you don't know them
And if you don't know them i think you need an update
And i mean usb-otg which doesn't work on cm roms
Oh I know what they are, guess I've always heard them, or referred to them as flash drives, that's odd asvi certainly don't live in a cave lol, I just really never heard them referred to as flash memories. Sorry, to bizarre lol
