Abstract
A BIMOS memory sense amplifier is provided having the low power dissipation and high noise immunity of CMOS devices while maintaining the high drive capability and switching speed associated with bipolar devices. A pair of differentially connected NPN transistors are coupled for receiving a first and a second bit current from the bit lines of a memory circuit. A MOS transistor circuit is coupled to the NPN transistors and is responsive to a differential output therefrom, for buffering two NPN push-pull output transistors.
