In this paper is presented a sense-amplifier-based physically unclonable function (PUF) with individually embedded non-volatile memory (eNVM) that offers 100% stable random bits. The proposed eNVM, which stores the initially generated random key, biases the sense-amplifier to reproduce always the same key as the initial value through a feedback path. In order to verify the performance of the proposed architecture, a 256-bit PUF with a core area of 0.160 mm 2 was implemented in a 180 nm standarddoi:10.1109/access.2019.2961967 fatcat:zdbavodbovh33a5l5htq7eaufu
