ABSTRACT:
A sense amplifier is provided for a bipolar random access memory that has memory cells arranged in a column and a pair of bit lines for said column of memory cells. A first bipolar transistor has its collector-emitter path coupled to one of the bit lines of a pair, and a base coupled through a diode means to the second bit line. A second bipolar transistor has its collector-emitter path coupled to the second bit line and its base coupled through a second diode to the first bit line. The collectors of both of the bipolar transistors are coupled to provide an output signal. Resistors are coupled to a pulse source and to both of the bases of the bipolar transistors. A current sink is coupled to both of the select bit lines. The diode means are connected so as to be forward biased when the base-emitter junction of the transistor to which the diode means is coupled is also forward biased.
