Instead of memorizing the whole chart just memorize the bottom parts of it. So if suited kings goes down to K9, just memorize that, suited Queen and jacks the same way. Same with unsuited broadway cards.
It helps to make the charts yourself so you have to actually write it down. Then compare each chart to each position and see what’s changing. Don’t forget to make charts as your stack size changes. It’s work but it’s worth and. Then put it in a binder and you will always have it. Soon it just becomes muscle memory.
Hope this helps.
