Counterfeit IC Countermeasure with 4T Cell Based Authentication Circuit

Pagination or Media Count:
A simple and compact authentication circuit based on a 4T bit cell is proposed for counterfeit detection and avoidance. The PUF-based authentication circuit has been designed to reduce or eliminate the reluctance of COTs manufacturers to include on-chip fingerprints by not requiring additional die area, IO pins, or read-out circuits and by using a deep-sleep mode during normal circuit operation so that it does not interfere with operation of the main IC.
