Having such a memorization mechanism that allows you to have a decent starting hand chart in your head is only going to help you in very very early stages of learning the game.
There are a lot of books and poker strategy websites where such charts can be found. I've noticed that those charts encourage you to play your hand if it's strong (medium to big pocket pairs, AK, AQ, KQ, even AJ). There are 2 main problems with this:
- you get hands that fit that criteria rarely. Maybe 1 in 30 hands. Playing very few hands like this is a guaranteed loss because in tournaments for example blinds keep going up and they'll kill your stack very quickly.
- if you only play those strong hands, you become extremely predictable. Your opponnents may just all fold preflop when they see you limp or raise instead of folding. They know you have a good hand, otherwise you wouldn't be playing it. You only win a few blinds and antes like this (which usually is not very much).
Like I said in the beginning: these starting hand charts are only good if you're completely new to the game and need to learn its very basic mechanics first. Once you know that, relying on those charts is extremely dangerous and unprofitable. You can't just wait for premium hands to show up (because they rarely do), you have to get your chips in the middle and be more aggressive with a wider range. On top of all this, poker is not so much about your hand, it's more about your opponent(s) hand(s) and his/their behaviour (but this is a completely new topic, outside of the scope of this answer).
If, after reading all this, you still want a memorization trick for this kind of thing, use Tom Au's answer, it's close enough.
