Abstract
A device is provided. The device includes: a plurality of physically unclonable function (PUF) cells, each of the plurality of PUF cells including at least one logic gate and being configured to generate an output signal based on at least one threshold level of the at least one logic gate; a signal generator configured to generate an input signal that is provided to each of the plurality of PUF cells; and a controller configured to, in a test mode, generate a control signal to control the signal generator to vary the input signal to control the plurality of PUF cells to output a plurality of output signals according to the input signal, and identify at least one weak PUF cell from among the plurality of PUF cells based on the output signal generated by the at least one weak PUF cell being an unstable output signal. The controller is further configured to disconnect the plurality of PUF cells from the signal generator in a normal mode.
