    摘要: A method is described that comprises modulating the power consumption of an SRAM as a function of its usage at least by reaching, with help of a transistor, a voltage on a node within an operational amplifier's feedback loop. The voltage is beyond another voltage that the operational amplifier would drive the node to be without the help of the transistor. The voltage helps the feedback loop establish a voltage drop across a cell within the SRAM.

    摘要: Reduction of standby leakage current in an internal circuit block using a transistor stack effect. For one embodiment, an apparatus includes a standby leakage reduction circuit to be coupled to the circuit block including a plurality of logic gates.

    摘要: A stack device is provided to obtain a stack effect. The stack device includes at least first and second active components. The first and second active components have first and second device widths, respectively. The first and second device widths are then selected to provide a desired leakage current and gate delay time for the stack device. The selection includes adjusting the first and second device widths while keeping a sum of the device widths constant.

A gate drive circuit is included to apply a first boosted gate drive voltage to a gate of the first leakage control transistor during an active mode of the internal circuit block. The gate drive circuit furthers applies a standby gate voltage to the gate during a standby mode of the internal circuit block, the standby gate voltage to cause a gate to source voltage of the leakage control transistor to be reverse-biased.
