I don't know of any methods to generically improve memory, but repetition and/or writing have always helped me. Repetition is what it sounds like: say or think what you're trying to memorize to yourself many times. Writing (NOT typing, but actual handwriting!) and taking notes also help, and can be used in conjunction with repetition. The most effective unintentional method of memorization is to be profoundly embarrassed or frightened by forgetting or not knowing something - it will stick with you forever. I don't know of any way to systematize that though.
