CIRCUIT STRUCTURE FOR PUF, PUF DATA OBTAINING METHOD, AND ELECTRONIC DEVICE

The present application provides a circuit structure for a PUF, a PUF data obtaining method, and an electronic device. The circuit structure comprises: a storage matrix which comprises a plurality of storage units, wherein a formation voltage is applied to each storage unit; a reading unit used for reading a formation resistance value of each storage unit after the formation voltage is applied to the storage unit, and transmitting the formation resistance value to a comparison unit; and the comparison unit used for comparing the formation resistance value with a preset resistance value, determining PUF data according to a comparison result, and outputting the PUF data. Compared with the prior art, due to the fact that the resistance value distribution of the storage units is not converged, the PUF is achieved more easily, and the manufacturing costs of various chips can be saved. La présente application fournit une structure de circuit destinée à une PUF, un procédé d'obtention de données de PUF, et un dispos
