"Summon up" means to bring something to mind or to evoke a feeling or memory that you had forgotten about. You can use this expression when you're trying to remember something, like the name of a person or a place, or when you're trying to recall a past experience or emotion. For example, if you're telling a story about a fun day you had with your friends, you might say, "I'm trying to summon up the memory of that day because it was so long ago."
