Concealable physical unclonable functions using vertical NAND flash memory

Abstract Physical Unclonable Functions (PUFs) can address the demand for enhanced hardware security. Vertical NAND (V-NAND) flash memory is the most commercialized non-volatile memory. However, it has been optimized to reduce cell-to-cell variation for stable data storage, which presents challenges...
