PHYSICALLY UNCLONABLE FUNCTION CODE GENERATING SYSTEM AND GENERATING METHOD

Abstract: a physically unclonable function (puf) code generating method includes the following steps. in a step (a), m�n memory cells in a memory cell array of a non-volatile memory are controlled to have an identical storage state, wherein m and n are positive integers, and m�n is greater than 1. in a step (b), x memory cells are selected from the memory cell array multiple times, and a virtual array is established, wherein the virtual array contains plural electrical characteristic combinations, and x is a positive integer smaller than m�n. in a step (c), the plural electrical characteristic combinations are selected from the virtual array multiple times, and a multi-bit puf code is generated.
