A random bit circuit includes four storage cells controlled by four different word lines. The first storage cell and the second storage cell are disposed along a first direction sequentially, and the first storage cell and the third storage cell are disposed along a second direction sequentially. The third storage cell and the fourth storage cell are disposed along the first direction sequentially. The first storage cell and the fourth storage cell are coupled in series, and the second storage cell and the third storage cell are coupled in series.

Random bit circuit capable of compensating the process gradient

A true random number generation system includes a physical unclonable function (PUF) entropy device, a pseudo random number generator, and an encoding circuit. The PUF entropy device is used for generating a random number pool. The pseudo random number generator is used for generating a plurality of first number sequences. The encoding circuit is coupled to the PUF entropy device and the pseudo random number generator for generating a plurality of second number sequences according to the plurality of first number sequences and a plurality of third number sequences selected from the random number pool.

PUF-based true random number generation system

An entanglement and recall system includes an antifuse-type PUF cell array and a processing circuit. The antifuse-type PUF cell array generates at least one key. The processing circuit is connected with the antifuse-type PUF cell array to receive the at least one key. While an entanglement action is performed, the processing circuit receives a plain text and the at least one key and generates a cipher text according to the plain text and the at least one key. While a recall action is performed, the processing circuit receives the cipher text and the at least one key and generates the plain text according to the cipher text and the at least one key.
