What makes you think your memory is used up?
If you issue 'free' and only look at the 'free' - column (I hope
you get what I mean), you may see very little memory left.
But that does not necessarily mean, that all your memory is used
up. Look at the cached column. If this has a considerable amount
of your memory, then that is no reason to worry. Your kernel
simply uses free memory to cache the files you already read.
This memory area can be viewed as beeing free.
