Well actually what I ment was a memory for storing data like weather, names etc
In computing hardware, "memory" and "storage" are not the same things. "Memory" is the what is used to process things. "Storage" is where you store thing for long term use.
In a PC, "Memory" is RAM and "Storage" is a Hard Drive (or similar device).
I make this distinction because many people say "memory" when they are referring to storage. So, there are shields and libraries available that expand the storage capability of an Arduino with a SD card.
