Latest Patents
One of his latest inventions is the "Self-testing input/output pad." This invention teaches an apparatus for testing the circuitry in an input/output (I/O) pad without probing the contact site on the I/O pad. A dominant driving circuit has an output coupled to a first contact site on a semiconductor chip, while a subordinate driving circuit also has an output coupled to the same site. A test control circuit sets up a drive fight between the dominant and subordinate driving circuits, selecting a stronger drive strength for the dominant circuit. This drive fight produces a test value at the first contact site, which is then transferred to a second contact site on the semiconductor chip for external probing.
Another significant patent is for an "Integrated circuit having memory built-in self-test (BIST) for different sizes." This application-specific integrated circuit (ASIC) features a CPU module and a memory module connected to the CPU. The memory size can be selected from a set of alternative sizes, and the CPU includes a memory test device that can test a memory module of any of these sizes based on received size codes.
