Circuit structure for PUF, method for obtaining PUF data and electronic equipment

The invention provides a circuit structure for a PUF, a method for obtaining PUF data and electronic equipment, and the circuit structure comprises: a storage matrix which comprises a plurality of storage units, wherein a formation voltage is applied to each of the storage cells; a reading unit which is used for reading a formation resistance value of each storage unit after the formation voltageis applied to the storage unit, and transmitting the formation resistance value to a comparison unit; and the comparison unit which is used for comparing the formed 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 distribution of the storage units is not converged, the PUF function is achieved more easily, and the manufacturing cost of various chips can be saved. 本申请提供一种用于PUF的电路结构、获取PUF数据的方法及电子设备，该电路结构包括：存储矩阵，所述存储矩阵包括多个存储单元；其中每个所述存储单元被施加形成电压；读取单元，用于读取每个所述存储单元被施加形成电压后的形成阻值，
