RE: hardware key
RE: hardware key
A combinatorial logic with N inputs may have 2^(2^N)
possible states. Any bit of memory is equivalent to
an input so N = number of (inputs + memorybits )
A 1Kbit memory will have two to the
1.27x 1,000,000,000,000,000,000,000,000,000,000 possibilities.
There is one way: autopsy the chip and measure under
microscope with micromanipulator -- a major project.
