To memorize Chinese characters: look at them, then break them down into their componenents, then try to write them, then compare what you wrote with the character then remember all that.

Likewise, it’s entirely possible to know a the meaning of a sound without knowing the character. Eventually however your knowledge of SOUND and IMAGE will line up!
