top shows high memory used but processes don't add up

When I do a top on Red Hat Linux I see high memory used. But when I add up the memory being used by all the processes it's not even nearly as much as I see in top. So for eg: I see that out of 6G Mem around 5.5G is in use. But If I add up memory being used by all the processes it's only around 3G.
