I am afraid bonsai for monocotyledons are very difficult if not impossible. But I am not sure if that's what you mean with meme plant? Palms, such as the Date palm, are not really trees (such as real bonsai) and therefore the techniques applied to bonsai do not work here.

The seed would in theory be able to germinate in a small pot, but would need a bigger pot as soon it gets bigger. Date seeds should germinate well in just normal potting soil (kept a bit wet). It could take a few weeks to months though.

So making a miniature palm in a 6 cm diameter pot is according to my knowledge and experience impossible.
