If I have a memory then how is that 'knowing' impermanent. I remember things from 20 years ago. If they are gone how come they can manifest here in my memory? I guess it is like how can I look at a painting I did 20 years ago right? But it might be an interesting question that others might have thoughts about. It's more to it than just a painting because a painting is just like this physical thing but a memory can be quite extensive. It is similar to things you never notice are amazing such as how you can speak and comprehend language.
