ABSTRACT:
A sense amplifier with an integral logic function for use in a circuit such as a tag cache portion of a microprocessor cache. In one form, the integral logic function is an exclusive-OR function. The sense amplifier senses a differential voltage developed between a differential pair of bit lines which are coupled to predetermined bit positions of a plurality of entries in a tag cache. While sensing the voltage, an exclusive-OR function is performed between the logic state of the sensed bit and a corresponding input address bit. If the input address bit matches the sensed bit, then a match signal is asserted. The value of the corresponding input address bit configures the circuit either to provide an output signal in a predetermined logic state if a true bit line signal voltage exceeds a complement bit line signal voltage, or to provide the output signal in the predetermined state if the complement bit line signal voltage exceeds the true bit line signal voltage.
