This is not black magic.  Many programmers do this, including the
boxes manufactured here at Data I/O.  Most semiconductor manufacturers
these days install a 2-byte code in each device which identifies
who the manufacturer of the device is and what specific device it
is.  The code can typically be extracted by supplying a super-voltage
to one of the address pins and reading the data lines.

The spec sheet for any device which has this feature will explain
how it works.
