A clock stretcher mechanism is provided for shifting a rising edge of a negative active global clock signal beyond a rising edge of a feedback path signal. A negative active global clock signal and a clock chopper signal are received in a base block. First base block circuitry modifies the clock chopper signal in order to form the feedback path signal. Second base block circuitry shifts the rising edge of the negative active global clock signal beyond the rising edge of the feedback path signal using a delay negative active global clock signal.

A memory array is provided that comprises a plurality of global bit lines such that each bit line is coupled to a plurality of memory cells. The memory array further comprises a plurality of precharge logic such that each precharge logic is coupled to an associated global bit line in the plurality of global bit lines. Identification logic in the memory array is coupled to the plurality of precharge logic. The identification logic provides a precharge enable signal to a subset of the plurality of precharge logic on each clock cycle such that the subset of precharge logic precharges its associated subset of global bit lines to a voltage level of a voltage source, thereby reducing the power consumption of the memory array.

Enhanced power savings for memory arrays

A technique for generating an adjustable boost voltage for a device includes charging, using first and second switches, a capacitor to a first voltage during a charging phase. The technique also includes stacking, using a third switch, a second voltage onto the first voltage across the capacitor in a boost phase to generate a boost voltage. In this case, the boost voltage is applied to a driver circuit of the device only during the boost phase and at least one of the first and second voltages is adjustable, thereby making the boost voltage adjustable.
