ABSTRACT:
Off-chip driver and receiver circuits for multiple level memory applications including a voltage sensing circuit that provides an output voltage adjust signal having different voltage levels corresponding to different external voltage levels of the memory circuit. The off-chip driver circuit is connected to the voltage adjust signal and has an output signal transition slew rate that varies in response to the voltage level of the voltage adjust signal. The circuit is also connected to the voltage adjust signal and includes a filter circuit having a time constant that adjusts the noise immunity of the receiver in response to the voltage level of the voltage adjust signal.
