Your words are attractive and friendly to memories which I'd like to learn by heart.
(PS: "which I'd like to learn by heart" is used to discribe the subject "words", I don't know whether I'm clear or not)
Your meaning is clear, if you meant you want to learn "memories" by heart. Sometimes, punctuation helps when writing to make things clear. So for example, you might write:
Your words--attractive and friendly to memory--are what i'd like to learn by heart. That sentence says that it is the words you'd like to learn by heart. In speaking, there is a pause, and a change in inflection, which tells the listener that "attractive and friendly to memory" is an explanatory phrase which you've put in the middle of the sentence, while preserving the reference to "words."
