Your question got me curious so I searches the net and here is what I got.

Memorize concepts, not content. ... - I practice this step most of the time. Just memorizing will not help you. If you forgot even just one word, you're doomed!
Chat up audience members before your presentation. ...-Don't know about this one. I usually don't talk to anyone before speaking in front. I tend to forget things.
Enhance your visuals and audio. ...- this is a must. Pictures usually make you remember things. If you are memorizing try to associate it with pictures. The moment you see the picture you will remember the things you memorized.
Flip your mindset to ease your nerves. ...- think only of positive things. Negative things will do no good to your nerves.
Get interactive.-

I think the most important one is practice. You may be nervous but if you're prepared nothing can go wrong.
