Abstract
A method and a circuit for protecting at least one element of an integrated circuit, including conditioning the operation of the element to be protected to the state of a signal conditioned by an irreversibly programmable element, the state of which is set during a probe test of the integrated circuit.
Claims5
A method for protecting at least one element of an integrated circuit, comprising conditioning the operation of the element to be protected to a state of a signal conditioned by an irreversibly programmable element, a state of which is set during a probe test of the integrated circuit.
An integrated circuit, comprising at least one element for protecting access to at least one function of the circuit, a state of which is irreversibly programmed by application of a signal on a pad of the circuit during a probe test.
