  • Publication number: 20160091908
    Abstract: A circuit includes an evaluation node through which current flows from a voltage source node to a sensed switch when the sensed switch is closed. First and second control switches are disposed between the voltage source node and the evaluation node to switch between first and second current paths for the current. The current passes through the first control switch when flowing along the first current path. The second control switch is coupled to a control terminal of the first control switch to deactivate the first control switch and allow the current to flow through the second current path. Multiple passive circuit elements are configured to establish first and second current levels for the current. The passive circuit elements are disposed between the voltage source node and the evaluation node in a circuit arrangement in which no current path to ground is present when the sensed switch is open.

  • Patent number: 9297855
    Abstract: An electronic design automation (EDA) tool for increasing the fault coverage of an integrated circuit (IC) design includes a processor that inserts at least one XOR gate, an AND gate, an OR gate and a multiplexer between observation test points and an existing first scan flip-flop of the IC design. The XOR gate provides an observation test signal to the first scan flip-flop by way of the AND gate, the OR gate, and the multiplexer such that the observation test signal covers the presence of faults at the observation test points. The first scan flip-flop outputs a data input signal, a set of test patterns, and a first set of test signals based on the observation test signal to indicate whether the IC design is faulty or not. A testable IC that can be structurally tested is fabricated using the IC design.

  • Patent number: 9298554
    Abstract: A fail-safe booting system suitable for a system-on-chip (SOC) automatically detects and rectifies failures in power-on reset (POR) configuration or boot loader fetch operations. If a failure due to a boot loader fetch occurs, a POR configuration and boot loader are fetched from a different non-volatile memory. The reloading takes place from further different non-volatile memory sources if the boot loader fetch fails again. The automated system operates in accordance with a state machine, and does not involve any manual, on-board switch selection or manual re-programming.

  • Patent number: 9299856
    Abstract: Fluorine is located in selective portions of a gate oxide to adjust characteristics of the gate oxide. In some embodiments, the fluorine promotes oxidation which increases the thickness of the selective portion of the gate oxide. In some embodiments, the fluorine lowers the dielectric constant of the oxide at the selective portion. In some examples, having fluorine at selective portions of a select gate oxide of a non volatile memory may reduce program disturb of the memory.
