—Physically Unclonable Function (PUF) is a security primitive to address hardware security issues such as chip authentication, Intellectual Property (IP) protection etc. Conventional CMOS PUFs are built on delay (inverter chains, scan chains etc.) or memory structures (like SRAM). In this paper, we propose a novel PUF which works on the principles of(More)
Non-volatile memories are gaining significant attention for embedded cache application due to low standby power and excellent retention. Domain wall memory (DWM) is one possible candidate due to its ability to store multiple bits/cell in order to break the density barrier. Additionally, it provides low standby power, fast access time, good endurance and(More)

Spin Transfer Torque RAM (STTRAM) is a promising candidate for Last Level Cache (LLC) due to high endurance, high density and low leakage. One of the major disadvantages of STTRAM is high write latency and write current. Additionally, the latency and current depends on the polarity of the data being written. These features introduce major security(More)
