    Abstract: An integrated circuit comprising a detection circuit portion (102) for detecting an electromagnetic pulse attack on the integrated circuit is provided. The detection circuit portion (102) comprises a shadow flip-flop (106) comprising a clock input and a clock net (126) connected to said clock input. The detection circuit portion (102) also comprises a clock gate (124) connected to the clock net (126), wherein the clock gate (124) is controlled by an enable signal so as selectively to be in an open state in which the clock gate (124) passes a clock signal to the clock net (126) or in a closed state in which the clock gate (124) does not pass the clock signal to the clock net (126). The detection circuit portion (102) further comprises an error circuit portion (117), wherein the error circuit portion (117) is arranged to selectively output an error signal if: the shadow flip-flop (106) is clocked by a signal from the clock net (126) and the clock gate (124) is in the closed state.

    Abstract: Technologies for signal skew correction in integrated circuit memory devices are described. An integrated circuit memory device includes a first interface to receive command/address (CA) signals and a clock signal, a data interface, and a mode register. During a CA bus loopback mode, the first interface receives a pattern of CA signals and the clock signal and the data interface outputs the pattern of CA signals. During the CA bus loopback mode, the mode register can be programmed with a value representative of a timing offset between the clock signal and a sampling point for the first interface.

    Abstract: A system for data creation, storage, analysis, and training while margin testing includes a margin test generator coupled through an interface to a Device Under Test (DUT). The margin test generator is structured to modify test signals for testing the DUT during one or more testing states of a test session to create testing results. The testing results are stored in a data repository along with a DUT identifier of the DUT tested during the test session. A comparator determine whether any results of the DUT test results match a predictive outcome that is based from an analysis of previous DUT tests. If so, a message generator produces an indication that the tested DUT matched the predictive outcome.
