An integrated circuit for a physically unclonable function (PUF) includes first and second PUF cells and a combination circuit. The first and second PUF cells respectively output first and second cell signals having unique levels based on a threshold level of a logic gate. The combination circuit includes a first stage that generates a first combination signal based on the first and second cell signals. The first and second PUF cells respectively include first and second logic gates to respectively output the first and second cell signals. The combination circuit includes a third logic gate that receives the first and second cell signals and outputs the first combination signal. The third logic gate has a same structure as each of the first and second logic gates.

Integrated circuit for physically unclonable function and device including the same

A physical unclonable function (PUF) circuit and a PUF system including the same are provided. The PUF circuit includes a plurality of PUF cells each configured to generate an output voltage by dividing a power voltage, a reference voltage generator configured to generate a first reference voltage by dividing the power voltage, and a comparing unit configured to sequentially compare the output voltages of the plurality of PUF cells with the first reference voltage to output data values of the plurality of PUF cells.

Physically unclonable function circuit, and system and integrated circuit including the same

A computer apparatus includes an information processing unit that processes information, a storing unit having a storage space in which the information being processed is stored, a main power supply that supplies power to the information processing unit, an auxiliary power supply including a thermoelectric element that converts heat generated in the computer into auxiliary power, and a controller that controls the auxiliary power supply to supply the auxiliary power to the information processing unit and the storing unit if it is determined that supply of power from the main power supply is interrupted, and controls the information processing unit to store the information to be processed by the information processing unit in the storing unit.
