How to memorize suttas? I was watching a video about the oral tradition in relation to how the suttas was first communicated and conveyed to monastics and lay people.

I was wondering what techniques buddhist monastics and lay people used/are using to memorize suttas. I know of chanting as an effective method. 

Are there other methods used within Buddhism?

Thank you for your time.
The best way to "memorize" suttas is to get the key idea or sanna of the given sutta. It is the “learning” of true dhamma and not “memorization” that will help in the retention of key phrases. For that one needs to get the key idea or sanna of a given concept. When one gets the sanna of a concept, one will never lose it.

So, the best way to memorize is to grasp the concepts of dhamma. Then it becomes easier to analyze a given concept as one progresses. The more one grasps about a concept and the meanings and how to use them in other situations, things start to come flowing through. This is unlike memorizing the wording, but another will think that you’ve memorized a given thing.

The basic difference between “real learning” and memorization is that in the first case you have acquired the ability to grasp concepts, whereas the latter makes you just blindly follow rules/instructions.

This is a concept that is hard to grasp for many these days, because we are so much used to “book learning”. There are many people who can repeat certain tasks mechanically without even bothering to think through. And then when the situation changes somewhat they do not know how to handle the “new situation”.
