Strange enough, these figures are missing here, however, they can be
derived from the other figures.

It means that your memory is in use, but the biggest part of it (314MB)
is caches which can easily be freed but are kept in memory to increase
performance (disk is slow, as long as the memory would be empty
otherwise, keeping it as cache is a good thing since re-reading it from
disk would cost far more time than just using the cached data).
So actually you have about 320MB of memory left, but it's mostly used to
cache data (which is good! Why should your OS not use it, if it's
there ...). As soon as some application needs more memory it will free
caches, which does hardly cost any effort / time.
Also the fact that your swap space is not utilized is a sign that your
amount of memory is high enough and that everything fits in there
