Does it use php function serialize() or some internal function of memcache extension? If it uses serialize(), then I can serialize my data myself with json_encode, for example. Will it be faster?

The documentation of Memcache::set says (quoting) :
Strings and integers are stored as is, other types are stored serialized.
So I'm guessing it uses serialize internally ;-)
A good way to speed up the serialization/deserialization process would be to replace the internal default PHP serializer with something like [**igbinary**][2].
There are a couple of notes about that in theses slides presented by Ilia Alshanetsky a couple of weeks ago at the Forum PHP 2010 in Paris : APC & Memcached the High Performance Duo
