    Abstract: A circuit for preventing multi-bit upsets induced by single event transients is described. The circuit comprises a clock generator configured to generate a first clock signal and a second clock signal; a first memory element configured to receive a first input signal and generate a first output signal, the first memory element having a first clock input configured to receive the first clock signal; and a second memory element configured to receive the first output signal and generate a second output signal, the second memory element having a second clock input configured to receive the second clock signal; wherein the first clock signal is the same as the second clock signal. A method of preventing multi-bit upsets induced by single event transients is also described.

    Abstract: The disclosed IC includes a load circuit and a temperature sensor circuit. The temperature sensor circuit measures temperature of the IC and stores temperature data in a register. An SEL mitigation circuit monitors the IC for a temperature change indicative of an SEL. A temperature change greater than a threshold over a time interval is indicative of an SEL. The SEL mitigation circuit is configured to reduce voltage applied to the IC to a voltage level that clears an SEL in the IC in response to a temperature change exceeding the threshold and to increase voltage applied to the load circuit after the reduction in voltage.

    Abstract: Examples described herein provide a circuit and methods for self-testing to detect damage to a device, which damage may be caused by an Electro-Static Discharge (ESD) event. In an example, an integrated circuit includes an input/output circuit, an ESD protection circuit, and a system monitor. The input/output circuit has an input/output node. The ESD protection circuit is connected to the input/output node. The system monitor has a driving/measurement node selectively connectable to the input/output node. The system monitor is configured to drive and measure a voltage of the driving/measurement node. The system monitor is further configured to determine, based on driving and measuring the voltage of the driving/measurement node, whether a damaged device is present. The damaged device is in the input/output circuit or the ESD protection circuit.

    Abstract: Embodiments herein describe techniques for wafer to wafer stacking of integrated circuit chips (e.g., dice) to form stacked IC devices. In one example, a stacked IC device is provided that includes a first wafer, a second wafer, and first conductive bridge. The second wafer is stacked on and secured to the first wafer. The second wafer has a plurality of IC dice that are communicatively coupled to a plurality of IC dice formed on the first wafer. The first conductive bridge has a first end that is sandwiched between the first and second wafers. The first conductive bridge shorts exposed pads of dice formed in the exclusion zones of the first and second wafers.
