How can I find out the original model number by marking code and top mark?

As you know, sometimes we need to look for the characteristics of a chip, and we don't have a specific model. We need to look for it through imprinting, and that's when we need a good method.

Those top marking codes are the original model number for that chip.

A good method is not good enough!
The best method through imprinting. Is the first thing you see when you're born.
