  • Low-leakage level shifter with integrated firewall and method
    Patent number: 7342417
    Abstract: A level shifter may reduce leakage current and provide firewall protection between circuits of different voltage domains when one voltage domain is in a standby mode. The level shifter may either couple or decouple input circuitry from a reference voltage in response to a firewall enable signal, may translate signals between a first voltage domain and a second voltage domain when the firewall enable signal is deasserted, and may generate an output signal having a predetermined one of either a high or low state when the firewall enable signal is asserted.
    Type: Grant

    Date of Patent: March 11, 2008
    Assignee: Marvell International Ltd.
