Here is an introduction to memcached and PHP:

As far as using memcached from CI, I imagine you would want to either add the caching code directly into your models, or from your Controllers you would want to check the cache before querying data from a model.

public function index()
    {
        // manual connection to Mamcache
        $memcache = new Memcache;
        $memcache->connect("localhost",11211);

        $data=$memcache->get("test_key");

        if($data){
            echo 'cache data:';
            var_dump($data);
        }else{
            $data=$this->db->query("SELECT count(*) as ca FROM table WHERE typ=1 ")->row();
            $memcache->set("test_key",$data,false,10); // 10 seconds
            echo 'real data:';
            var_dump($data);
        }

    }
