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.
