Electronic fingerprinting of semiconductor integrated circuits |
摘要 |
A method of identifying an integrated circuit device based on the initial state of certain memory cells within a memory array of the integrated circuit device. For many cells in the memory array the initial state is relatively consistent at each power-up, due to mismatches between the transistors that form each memory cell. Thus these consistent initial states provide a signature of the memory array and the integrated circuit device.
