    摘要: A semiconductor memory device for reducing ripple noise of a back-bias voltage, and a method of driving the semiconductor memory device include a word line driving circuit and a delay logic circuit. The word line driving circuit enables a sub-word line connected to a selected memory cell to a first voltage, and disables the sub-word line of a non-selected memory cell to a second voltage and a third voltage, in response to a sub-word line enable signal, a first word line driving signal, and a second word line driving signal. The delay logic circuit controls the semiconductor memory device so that an amount of charge of the sub-word line that is introduced to the third voltage is greater than an amount of charge of the sub-word line that is introduced to the second voltage by changing a transition point of time of the sub-word line enable signal with respect to a transition point of time of the first word line driving signal, during the disabling of the sub-word line.

    摘要: Devices, circuits and methods for dual voltage generation using a single charge pump. The dual voltages can be the same or different, as they are for two different components of a device. An oscillator generates an oscillating signal, and a charge pump generates a pumping voltage at a pumping node responsive to the oscillating signal. A first switching circuit is coupled to the pumping node, and outputs from the pumping voltage a first voltage to the first component. A second switching circuit is coupled to the pumping node, and outputs from the pumping voltage a second voltage to the second component. The first and second output voltages may optionally be sensed. The oscillator may be triggered and the first and second switching circuits may be controlled as needed to maintain the sensed first and second voltages at desired values and/or ranges.
