This manuscript addresses a novel ternary content addressable memory (TCAM) based physical unclonable function (PUF) with improved reliability and uniqueness for security improvement. In order to use TCAM as a PUF in an application, the stability of its startup patterns needs to be assured under wide variety of conditions such as temperature and applied voltage. Furthermore, the startup patterns of different memories must be unique and contain sufficient entropy. This paper presents the simulation results of startup pattern of TCAM PUF and reliability test in various temperature and voltage conditions.
