Abstract: A security device generates a key based on a physically unclonable function (PUF). The security device includes a physically unclonable function (PUF) block, an integrity detector, and a post processor. The PUF block outputs a plurality of first random signals and a plurality of corresponding first inverted random signals each having a logic level opposite to that of each of the plurality of corresponding first random signals. The integrity detector determines data integrity of the plurality of first random signals by using the plurality of first random signals and the plurality of corresponding first inverted random signals. The post processor generates a first row key that includes validity signals satisfying the data integrity.

Abstract: A semiconductor device includes a physical unclonable function (PUF) cell array that includes PUF cells outputting first bits; a non-volatile memory that stores marking bits indicating whether the first bits are valid, first mask bits generated by masking second bits depending on parity of the second bits, and second mask bits generated by masking helper bits of the second bits, the second bits are valid bits from the first bits; an extracting unit that extracts the second bits from the first bits using the marking bits; an unmasking unit that unmasks the second bits using the first mask bits while receiving the second bits to provide the third bits; a bit decoding unit that compresses the third bits to fourth bits while receiving the third bits; and a block decoding unit that generates a security key by decoding the fourth bits and the second mask bits.
