Abstract:
A physical unclonable function (PUF) circuit and a PUF system including the same are provided. The PUF circuit includes a plurality of PUF cells each configured to generate an output voltage by dividing a power voltage, a reference voltage generator configured to generate a first reference voltage by dividing the power voltage, and a comparing unit configured to sequentially compare the output voltages of the plurality of PUF cells with the first reference voltage to output data values of the plurality of PUF cells.

Claim (Index 8):
The PUF circuit of  claim 7 , wherein the validity determining logic determines one of the plurality of PUF cells that has the output voltage, which is at a level equal to or higher than the second reference voltage, or at a level less than the third reference voltage, to be a valid PUF cell.
