In principle, no;  memcache is not supported as a database backend for 
any module.  The API plumbing is just not there.

However, it seems to me if you really, *really* wanted to, you could 
implement a registrar manually, bypassing registrar + usrloc.  You'd be 
doing a lot of manual contact management that usrloc takes care of, though.

Why would you want to do that, though?  If you desire the speed of a 
memory-only lookup table, you can just use usrloc with db_mode 0:

    http://kamailio.org/docs/modules/4.0.x/modules/usrloc.html#idp6002056

No database storage required at all.

If you really want to store contacts in memory but are not content with 
usrloc's memory-only mode because you want persistence across Kamailio 
restarts, there are numerous things you could do.  You could set up an 
in-memory table in MySQL, or a PostgreSQL "tablespace" that is 
physically located on a filesystem mounted on a tmpfs filesystem and/or 
ramdisk.  You could also just have a separate registrar server using Path.
