Patents by Inventor Liang-Chuan LEE

Liang-Chuan 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).

  • Integrated circuit, power verification circuit and power verification method
    Patent number: 11763912
    Abstract: A power verification circuit is provided. The power verification circuit includes a current source, a resistive random access memory (RRAM) cell and a Zener diode. The current source is coupled to a power terminal. The RRAM cell is coupled between the current source and a ground terminal. The Zener diode has an anode coupled to the RRAM cell and a cathode coupled to the power terminal. The impedance of the RRAM cell is determined by the power voltage applied to the power terminal.
    Type: Grant
