Ask HN: How did you master SDRAM connection design?

I am new to embedded PCB design. I can find lots of resources such as video tutorial or the schematics for the power, adc, dac, etc.But I cannot find any hands-on tutorial on SDRAM, neither software nor hardware connection. I don't know what those pins on SDRAM are for and how can I connect them to the MCU.Is there any book about this topic?

Well, it only proves Scratch is not good for kids learning math, and the paper has some weak points as pointed out in other posts.

Actually, my first reaction when I heard of Scratch was -- why are these poor kids forced to learn something they will never use in the future of their lives?

The paper got one thing right -- it doesn't make any sense to design visual language deliberately for kids education. It's like saying -- kid, you are so naive so you have to do visual programming, even though it is slow and inefficient. If you are the kid, will you feel good?

If I have to choose a programming language for kids, I will choose LOGO.

Code for visual! Not visual for code!

It shows potential but still remains a toy for now, reminding me of the looping app on iPad where you can add or remove loops to compose music. You will never fail, but that's the problem: improvisation often comes with risk and that makes us exciting. Can learn different things from other interesting web-based interfaces:
