In conventional digital VLSI design, one usually assumes that a usable circuit/system should always provide definite and accurate results. But in fact, such perfect operations are seldom needed in our non digital worldly experiences. The world accepts " analog computation, " which generates " good enough " results rather than totally accurate results [1].(More)
Physical unclonable function (PUF) leverages the immensely complex and irreproducible nature of physical structures to achieve device authentication and secret information storage. To enhance the security and robustness of conventional PUFs, reconfigurable physical unclonable functions (RPUFs) with dynamically refreshable challenge-response pairs (CRPs)(More)
—Content addressable memory (CAM) offers high-speed search function in a single clock cycle. Due to its parallel match-line (M L) comparison, CAM is power-hungry. Thus, robust, high-speed and low-power M L sense amplifiers are highly sought-after in CAM designs. In this paper, we introduce a parity bit that leads to 39% sensing delay reduction at a cost of(More)

Memory-based physical unclonable function (MemPUF) has gained tremendous popularity in the recent years to securely preserve secret information in computing systems. Most MemPUFs in the literature have unreliable bit generation and/or are incapable of generating more than one response-bit per cell. Hence, we propose a novel MemPUF exploiting the unique(More)
