There is no way that MemCached could do it at least at the current state
(and In my opinion there is also no need).
Cause Memcached does NOT have any idea about PHPs data structure or any
programming language's.
In case of php the data stored is as serialised string and if you want to
fetch only part Memcached would have to operate with some substrings and on
update try to squeeze back in and rewrite the whole syntax (like length/type
and so on).

If you want to partly fetch/update use different keys for each array
element:
For example $variable[0] = 'value'; becomes set('variable_0','value') ..

> I still have to transfer whole array to get one index. If I want to change
something, whole array has to be transfered again.

This indicates you are using MemCached the wrong way and your data should be
packed (splited) in a different manner (see above).
