The embodiments of the invention disclose a method and an apparatus for noise injection for physical unclonable function (PUF) generator characterization. In one embodiment, a physical unclonable function (PUF) generator includes: a PUF cell array that comprises a plurality of bit cells, wherein each of the plurality of bit cells comprises at least two access transistors, at least one enable transistor, and at least two storage nodes, wherein the at least two storage nodes are pre-configured with substantially the same voltages allowing each of the plurality of bit cells having a first metastable logical state; a PUF control circuit coupled to the PUF cell array, wherein the PUF control circuit is configured to access the plurality of bit cells to determine second logical states by turningon the at least one enable transistor and turning off the at least two access transistors of each of the plurality of bit cells; and a noise injector coupled to the PUF control circuit and the PUF cell array. 本发明的实施例公开一种用于物理
