Shueh-Mien J. Lee 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).

  • High-performance user programmable logic device (PLD)
    Patent number: 5046035
    Abstract: A programmable logic device having greater design flexibility through use of a plurality of programmable macrocells in conjunction with programmable gate arrays. Each macrocell includes a programmable reconfigurable register for receiving sum terms from the array, and an I/O terminal connected to receive an output from the programmable reconfigurable register. Two separate feedbacks from the macrocell to the gate array are provided. The first feedback has multiple inputs including the register output, and the second feedback has multiple inputs including the I/O terminal. Accordingly, the I/O terminal and the register can function independently.
    Type: Grant
    Filed: February 28, 1990
    Date of Patent: September 3, 1991
    Assignee: ICT International CMOS Tech., Inc.
    Inventors: Robin J. Jigour, Shueh-Mien J. Lee, Ali Pourkeramati
