Abstract:
An integrated circuit for a physically unclonable function (PUF) includes first and second PUF cells and a combination circuit. The first and second PUF cells respectively output first and second cell signals having unique levels based on a threshold level of a logic gate. The combination circuit includes a first stage that generates a first combination signal based on the first and second cell signals. The first and second PUF cells respectively include first and second logic gates to respectively output the first and second cell signals. The combination circuit includes a third logic gate that receives the first and second cell signals and outputs the first combination signal. The third logic gate has a same structure as each of the first and second logic gates.

Claim (Index 17):
An integrated circuit for a physically unclonable function (PUF), the integrated circuit comprising:\n a logic block including a plurality of PUF cells to respectively generate cell signals having unique levels determined based on threshold levels of a plurality of logic gates, the logic block to output an output signal corresponding to at least one of a plurality of cell signals based on a plurality of enable signals; and a controller to generate the plurality of enable signals including an activated enable signal to select at least one of the plurality of PUF cells and to generate a key of the integrated circuit based on the output signal.
