Abstract
A PUF code generation apparatus that includes a reference generator, a PUF information generation and storage array, a sensing amplifier and a writing driver is introduced. The PUF information generation and storage array includes a plurality of first memory cells each including a PUF information providing element and a PUF information storage element. The sensing amplifier compares a plurality of first electrical values read from the PUF information providing elements to a reference generated from the reference generator to generate a plurality of PUF information. The writing driver performs a write-back operation on the PUF information storage elements according to the plurality of PUF information. The sensing amplifier reads a plurality of second electrical values of the PUF information storage elements to generate a sensing result and output a PUF code according to the sensing result.
