Interactive basic logic chip teardown

http://siliconpr0n.org/wiki/doku.php?id=quiz:metal_gate_cmos

When I first started I wanted to dissect a basic logic chip but the ones I looked at had funny power transistors and so didn't work well for getting my feet wet.  However, there are plenty that do use more standard MOSFETs and so here's one such chip presented as an interactive quiz.  Each quiz goes increasingly deeper into the chip and ends with explanations so that you can move onto the next level.  Its designed to either test yourself or as a learning exercise.  If you don't know the answers just make a best guess and you should get enough info at the scoring page to move onto the next quiz.  Enjoy!
