How to use Memcached with multiple databases/applications in the same server?

I’m using Memcached to store the RBAC permissions on my application, and it has been working fine for a while.

However, now I will have multiple applications with different databases in the same server, and I have experienced conflicts between the applicattions because they all use the same Memcached instance. Is there a way to create a separated Memcached instance for every application?
