Content is what makes a website popular and memorable, not the design.
If you want the design to be "memorable", then just create an original and distinctive design. It's not hard to make a design that stands out (e.g. use loud colors, an animated background, and an annoying audio loop). What's hard is making a good design that stands out. That's a talent that great designers get paid a lot of money for having. As there's no magic formula that works every time, you're not likely to find a list of tips that can help you achieve this objective.
