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 15):
The PUF system of  claim 13 , wherein the reference voltages comprise a first reference voltage, a second reference voltage and a third reference voltage,\n the second reference voltage is higher than the first reference voltage, the third reference voltage is lower than the first reference voltage, the PUF circuit compares the output voltages of the plurality of PUF cells with the first reference voltage to generate data values of the plurality of PUF cells, and the PUF circuit determines data values of PUF cells having an output voltage between the second reference voltage and the third reference voltage, from among the plurality of PUF cells, to be invalid.
