Patents by Inventor Teoh Boon-Weng

Teoh Boon-Weng has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8981823
    Abstract: An apparatus and method for testing is provided. An integrated circuit includes a comparison circuit that is arranged to trip based on a power supply signal reaching a trip point. The integrated circuit also includes an analog-to-digital converter that is arranged to convert the power supply signal into a digital signal. The integrated circuit also includes a storage component that stores a digital value associated with the digital signal, and provides the power supply value at an output pin of the integrated circuit. The integrated circuit includes a latch that is coupled between the analog-to-digital converter and the storage component. The latch is arranged to open when the comparison circuit trips, such that, when the comparison circuit trips, the storage component continues to store a digital value such that the digital value corresponds to the voltage associated with the power supply signal when the comparison circuit tripped.

  • Patent number: 8094509
    Abstract: A memory includes memory arrays and boost converter circuitry. The boost converter circuitry provides at least one boosted voltage to each of the memory arrays when the memory array is being accessed. The boosted voltages may include a word line voltage, and/or a pass gate voltage provided to the gates of pass line transistor in a sector decoders and/or an array decoder for the memory cells being accessed. The boost converter circuitry includes at least two boost converters, and a switch. When one of the memory arrays is accessed, the switch either couples the boost converters together or does not couple the boost converters together based on the distance of the memory array being accessed from the boost converters.
