Back in the day we used to insert "memory cards" into cameras in order to store photos on them. You could transfer that memory card to a reader that was plugged into a PC and it would show up as a drive with files you could transfer to your computer's hard drive. Personally, I usually specify RAM or hard drive/storage just to make sure I'm clear, because "memory" is pretty ambiguous in my experience.
