More Information
Summary:The present invention provides a physically unclonable function (PUF) circuit including: a first array including at least one PUF cell; a second array including at least one PUF cell; and a control unit that selects a first PUF cell in the first array, selects a second PUF cell in the second array, and generates unique information indicated by the first PUF cell and the second PUF cell based on a first output voltage output by the first PUF cell and a second output voltage output by the second PUF cell. 본 발명은 적어도 하나의 PUF(physically unclonable function) 셀을 포함하는 제1 어레이, 적어도 하나의 PUF 셀을 포함하는 제2 어레이 및 상기 제1 어레이 내에서 제1 PUF셀을 선택하고, 상기 제2 어레이 내에서 제2 PUF셀을 선택하며, 상기 제1 PUF셀에 의해 출력되는 제1 출력전압과 상기 제2 PUF셀에 의해 출력되는 제2 출력전압에 기반하여 상기 제1 PUF셀과 상기 제2 PUF 셀이 나타내는 고유 정보를 생성하는 제어부를 포함하는 PUF 회로를 제공한다.
