SEMICONDUCTOR DEVICE AND OPERATING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device and an operating method thereof.

SOLUTION: A semiconductor device comprises: a voltage generator which generates a test voltage; a graphene transistor to which a gate-source voltage is applied on the basis of the test voltage; and a detector which detects whether the gate-source voltage is a Dirac voltage of the graphene transistor and outputs a feedback signal indicating whether the gate-source voltage is the Dirac voltage. The feedback signal is applied to the voltage generator.
