How do memory cards work?

I've really been intrigued by how so much of data gets stored in such a small chip, with visibly no PCB(printed circuit board)...





Please give proper genuine answers, I know what they look like and where they work, just tell me their working principle...

How do memory cards work?
I'm not quite sure what you mean. Memory cards is in RAM or GPU's? RAM (random access memory) is what programs use to run them. Usually, the more RAM, the better your computer runs and the programs have more space to be able to run the program at it's fullest. Games require more RAM to run.
