    • The invention provides micro-electromechanical switch (MEM) based designs for reducing the power consumption of logic blocks (e.g., latches) by isolating the logic blocks when they are non-operational. A power reduction circuit in accordance with the present invention comprises a logic block and at least one micro-electromechanical (MEM) switch for selectively disabling the logic block. MEM switches are provided for selectively: disconnecting the logic block from power; disconnecting the logic block from ground; providing a bypass line around the logic block; disconnecting an output of the logic block; and/or disconnecting an input of the logic block.
    • 本发明提供了基于微机电开关(MEM)的设计,用于通过在逻辑块不可操作时隔离逻辑块来降低逻辑块(例如,锁存器)的功耗。 根据本发明的功率降低电路包括逻辑块和用于选择性地禁用逻辑块的至少一个微机电(MEM)开关。 提供MEM开关用于选择性地:断开逻辑块电源; 断开逻辑块与地线的连接; 在逻辑块周围提供旁路线; 断开逻辑块的输出; 和/或断开逻辑块的输入。

    • A method and apparatus for adaptively adjusting the operating voltage of an integrated circuit in response to tester-to-system variations, worst-case testing techniques, process variations, temperature variations, or reliability wearout mechanisms. The minimum operating voltage of an integrated circuit is determined either during external testing of the integrated circuit or during built-in-self-testing. The minimum operating voltage is transmitted to a variable voltage regulator where it is used to set the output of the regulator. The output of the regulator supplies the integrated circuit with its operating voltage. This technique enables tailoring of the operating voltage of integrated circuits on a part-by-part basis which results in power consumption optimization by adapting operating voltage in response to tester-to-system variations, worst-case testing techniques, process variations, temperature variations or reliability wearout mechanisms. Alternatively, the invention enables adaptive adjustment of the operating frequency of an integrated circuit. The invention enables system designers to adaptively optimize either system performance or power consumption on a part-by-part basis in response to tester-to-system variations, worst-case testing techniques, process variations, temperature variations or reliability wearout mechanisms.
