( Mad Inventions)human memory

I would like to see a invention where the human memory can be increased like we are able to increase the memory of computers. A simple tablet should do the trick.As we get older we tend to forget a lot and would it not be perfect if we could remember new and old things very sharpely.Also instead of using paper and pen just bring information in your head via your brain
and remember every bit of it.Wouldn't that be great.
