The invention relates to a physically non-clonable function device with transistors, and a method for manufacturing same. In accordance with an embodiment, a physically unclonable function device includes a set of transistor pairs, transistors of the set of transistor pairs having a randomly distributed effective threshold voltage belonging to a common random distribution; a differential read circuit configured to measure a threshold difference between the effective threshold voltages of transistors of transistor pairs of the set of transistor pairs, and to identify a transistor pair in whichthe measured threshold difference is smaller than a margin value as being an unreliable transistor pair; and a write circuit configured to shift the effective threshold voltage of a transistor of theunreliable transistor pair to be inside the common random distribution. 本文描述了具有晶体管的物理不可克隆功能的器件及制造方法。根据一个实施例，一种物理不可克隆功能器件包括晶体管对集合，晶体管对集合中的晶体管具有属于共同随机分布的经随机分布的有效阈值电压；差分读取电路，被配置为测量晶体管对集合中的晶体管对的晶体管的有效阈值电压之间的阈值差，并且将其中所测量的阈值差小于裕度值的晶
