Abstract:
In certain aspects, an apparatus comprises a plurality of PUF cells. Each PUF cell comprises a first transistor in series with a first loading resistive component and coupled to a common cross-coupled node and cross-coupled to a complementary common cross-coupled node, a second transistor in series with a second loading resistive component and coupled to the complementary common cross-coupled node and cross-coupled to the common cross-coupled node, a first pass-gate and a second pass-gate coupled to a bit line and the complementary bit line, respectively. The apparatus further comprises an auxiliary peripheral circuit coupled to the bit line, the complementary bit line, the common cross-coupled node, and the complementary common cross-coupled node. During activation, the selected PUF cell, together with the auxiliary peripheral circuit, forms a cross-coupled inverter pair and outputs a physical unclonable function value.

Claim (Index 13):
The apparatus of  claim 1 , wherein one of the plurality of PUF cells is configured to be selected to output a physical unclonable function (PUF) value based on a mismatch of transistors of the selected one of the plurality of PUF cells.
