What an awesome write up.

I've only skimmed for now, but could you repeat this process for things like anti-fuse/efuse memory?

I've seen some commentary about preventing physical analysis, but I'm no expert.

Thank you so much! And yes anti fuse memory is also known as PROM, which the bits can be extracted using a metallurgical microscope! The ESP32 which I recently delayered , I believe had anti fuse memory
