Latest Patents

One of his latest patents is titled "Implementing logic security feature for disabling integrated circuit test ports ability to scanout data." This patent describes a method and apparatus for implementing integrated circuit security features that selectively disable testability features on an integrated circuit chip. The test disable logic circuit receives a test enable signal and, in response, establishes a test mode while disabling ASIC signals. When the functional mode is enabled, the test disable logic circuit prevents the test mode from being established while the integrated circuit chip is powered up.

Another notable patent is "Implementing enhanced security features in an ASIC using eFuses." This patent presents a method and eFuse circuit for implementing enhanced security features using eFuses. It includes a design structure that allows for the disabling of selected predefined test, debug, and mission security functions in application-specific integrated circuits (ASICs). The eFuse circuit comprises a plurality of eFuses, a sense amplifier, and a plurality of sense output latches, which work together to enable predefined security functions.
