Can't Save My Game

Saturday

I just downloaded F.F. V on my P.S. 3.
I found where it wants a memory card in slot one or two, and the memo save,
I am assuming that is for the original P.S one.
Is there any way I can play this game and save it to the P.S 3, or do I have to play it non-stop without being able to save.
I guess I am missing something, but I don't know what.
Thanks for any help.

Just figured out how to save. I found out how to assign the slots. Thanks anyway.
