The memory is used for 2 different things, one is for the main memory, which may help to opperate the opperating system, and the other is for video memory. The things I love about this console are; (A) it is very easy to opperate, (B) very quick when it is loading up, (C) Good picture quallity and sound quallity, (D) you get free online for it , unlike xbox live! There are many other things I like about this console but I won’t go into all of that. Overall the ps3 is a very good console and you should buy one, I know this because I own a Playstation 3 Slimline.
