The bias control circuit has a plurality of bias control lines that apply one or more bias control signals to each PUF cell in the array of PUF cells. The selector circuit selects a subset of the PUF cells in the array of PUF cells based on whether outputs of the PUF cells in the array of PUF cells change in response to application of the bias control signals. A corresponding method is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physically unclonable functions with enhanced margin testing","description":"Apparatus for identifying stable physically unclonable function (PUF) cells includes an array of PUF cells, a bias control circuit, and a selector circuit.
