Abstract
Embodiments of a physical unclonable function (PUF) device and a method for generating helper data for a PUF device with an array of cells are disclosed. In an embodiment, the PUF device comprises an array of cells, wherein each cell of the array generates an output signal, a reliable cell group detector coupled to the array of cells to find reliable groups of cells in the array of cells having sufficient reliable cells and output addresses of the reliable groups of cells, and a storage device coupled to the reliable cell group detector to store the addresses of the reliable groups of cells to be used as helper data for PUF response operations.
