Abstract
A reconfigurable PUF with two PUF functions comprises 2×n PUF cells, a sequential control module, a row selection module, n amplification modules, n first bit lines, and n second bit lines. Each of the 2×n PUF cells comprises a first PMOS transistor, a second PMOS transistor, a first NMOS transistor, a second NMOS transistor, a third NMOS transistor, a fourth NMOS transistor, a fifth NMOS transistor, a sixth NMOS transistor and a seventh NMOS transistor. The PUF cells can provide two independent responses, and can operate in a SRAM mode and an inverter mode. Therefore, the reconfigurable PUF with two PUF functions can operate both in the SRAM mode and the inverter mode, and a PUF operating mode with higher reliability is selected for generating final responses.
