Apparatus and methods implement a physical unclonable function (PUF) from NAND operations. A NAND flash memory device may generate an unclonable natural random sequence of bits based on a threshold voltage of a plurality of cells in a memory cell array. The unclonable natural random sequence may be stored starting at an address of the memory cell array. A selected subsequence of the unclonable natural random sequence may be stored in a first set of data latches, and target data may be stored in a second set of data latches. The NAND flash memory device may generate a physical unclonable function (PUF) output by applying an XOR operation to the target data and the selected subsequence. The PUF output may be stored in a set of registers or provided to a memory controller to be used for secure applications such as secure identity detection and secure data transfer.
