摘要： 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.

摘要： A level translator includes an NMOS input transistor and a PMOS input transistor having respective gates receiving an input voltage. The input transistors compare the input voltage to respective first and second supply voltages. The input voltage is also applied to an inverter that is powered by the first and second supply voltages. An output terminal is coupled to a third supply voltage through a PMOS output transistor and to a fourth supply voltage through an NMOS output transistor. The third and fourth supply voltages are outside of a range bounded by the first and second supply voltages. The respective drains of the input transistors and the output of the inverter are coupled to the gates of the output transistors in a manner that either turns the PMOS output transistor ON and the NMOS output transistor OFF or turns the NMOS output transistor ON and the PMOS output transistor OFF.
