AVR-Chat

You can use an electron microscope to read the memory according to
this PDF:

http://www.cl.cam.ac.uk/~mgk25/sc99-tamper-slides.pdf

If you know the precise location of the lock bit you might be able to
change its state by bombarding it with electrons.

If it were a simple job to read the memory of a "locked" AVR the lock
bit would be useless, right?

Have Fun!
