Abstract
An integrated circuit device can include a plurality of nonvolatile memory elements having values that vary randomly or pseudo-randomly from one another; a selection circuit configured to select a plurality of nonvolatile memory elements that vary randomly or pseudo-randomly in response to a received challenge value; and sense circuits configured to generate a response value based on the values of the selected nonvolatile memory elements. Related methods and systems are also disclosed.
