Abstract
Methods and apparatus for producing an electronic ID number include modifying at least one physical bit element from among each of at least first and second groups of physical bit elements, each physical bit element of each group having a first physical state in which it is operable to produce a signal having a first electrical state, and being capable of permanent modification to a second physical state in which it is operable to produce a signal having a second electrical state; and producing (i) one bit of an identification (ID) number from the respective signals issuing from each of the respective at least first and second groups of physical bit elements, and (ii) a validity signal indicative of whether the one bit of the ID number is valid.
Claims28
1. An apparatus, comprising:
- at least first and second groups of physical bit elements, each physical bit element of each group having a first physical state in which it is operable to produce a signal having a first electrical state, and being capable of permanent modification to a second physical state in which it is operable to produce a signal having a second electrical state;
- and
- at least first and second bit logic circuits, each being associated with a respective one of the at least first and second groups of physical bit elements, and each operable to produce (i) one bit of an identification (ID) number from the respective signals issuing from each of the respective at least first and second groups of physical bit elements, and (ii) a validity signal indicative of whether the one bit of the ID number is valid.
A method, comprising:
- modifying at least one physical bit element from among each of at least first and second groups of physical bit elements, each physical bit element of each group having a first physical state in which it is operable to produce a signal having a first electrical state, and being capable of permanent modification to a second physical state in which it is operable to produce a signal having a second electrical state;
- and
- producing (i) one bit of an identification (ID) number from the respective signals issuing from each of the respective at least first and second groups of physical bit elements, and (ii) a validity signal indicative of whether the one bit of the ID number is valid.
