    Abstract: A current sense amplifier may include one or more clamping circuits coupled between differential output nodes of the amplifier. The clamping circuits may be enabled during at least a portion of the time that the sense amplifier is sensing the state of a memory cell coupled to a differential input of the sense amplifier. The clamping circuits may be disabled during the time that the sense amplifier is sensing the state of a memory cell at different times in a staggered manner. The clamping circuits may be effecting in making the current sense amplifier less sensitive to noise signals.

    Abstract: A signal driver circuit having an adjustable output voltage for a high-logic level output signal. The signal driver circuit includes a signal driver configured to output a first logic level signal having a first voltage and output a second logic level signal having a second voltage according to an input signal. A voltage controlled voltage supply coupled to the signal driver provides the first voltage for the first logic level signal. The magnitude of the first voltage provided by the voltage controlled voltage supply is based on a bias voltage. A bias voltage generator can be coupled to the voltage controlled voltage supply to provide the bias voltage.
