What is 3D stacking and chiplets?

3D stacking and chiplets are like building blocks that help computers get smarter and faster.

Imagine you're making a tower out of LEGO bricks. Normally, you just keep adding bricks on top of each other, one layer at a time. That's how traditional computer chips work: all the parts are in one flat layer. But 3D stacking is like building your LEGO tower sideways too, you can stack layers next to each other or even on top of each other, making everything fit better and work faster.

Now think about chiplets. They’re like small, special LEGO pieces that do specific jobs. Instead of having one giant LEGO block for the whole tower, you use many smaller ones. These little chiplets can be used in different ways, some might handle numbers fast, others might remember things better, and they can even be swapped out if something breaks.

By combining 3D stacking with chiplets, we’re making computers like LEGO towers: faster, smarter, and easier to fix. It’s like having a toy box full of tiny, powerful helpers that work together!
