SEMICONDUCTOR DEVICE AND AUTHENTICATION SYSTEM

In order to realize a silicon PUF of lower power consumption, a semiconductor device includes first and second MIS transistors of the same conductive type in off-state coupled in series, as a PUF element. The PUF element outputs a signal of high level or low level depending on the potential of a con...

Zusammenfassung:In order to realize a silicon PUF of lower power consumption, a semiconductor device includes first and second MIS transistors of the same conductive type in off-state coupled in series, as a PUF element. The PUF element outputs a signal of high level or low level depending on the potential of a connection node of the first and the second MIS transistors. Preferably, the MIS transistors are fin-type FETs.
