DRAM-based PUF

⁤Securing systems with limited resources is crucial for deployment and should not be compromised for other performance metrics like area and throughput. ⁤⁤Physically Unclonable Functions (PUFs) emerge as a cost-effective solution for various security applications, such as preventing IC counterfeiting and enabling lightweight authentication. ⁤⁤In the realm of memory-based PUFs, the physical variations of available memory systems, such as DRAM or SRAM, are exploited to derive an intrinsic response based on the accessed data row. ⁤⁤This study introduces an innovative design of a DRAM-based PUF that utilizes the variations of adjacent DRAM cells to extract a reliable and secure key. ⁤ ⁤The dataset, which is used for validating the proposed design, is generated through Monte Carlo simulations implemented on the Cadence tool. ⁤⁤The simulation environment is configured, featuring 11 DRAM devices, each comprising 5K data rows and an 8-bit width. ⁤⁤Each DRAM device is associated with a folder containing voltage data collected for each bit, along with the corresponding evaluated response. ⁤⁤Additionally, the device folder contains a concatenated 8-bit response. ⁤
