Abstract
A sense amplifier uses a cascode stage ( or ) that receives a predetermined bit line pair differential signal and provides an output. The cascode stage output is coupled to a true and a complement output of the sense amplifier. In one form, a pair of pass transistors ( ) and an amplifier ( ) are coupled to the cascode stage and to complementary outputs and are controlled by a sense enable signal. The amplifier is operative only when the pair of pass transistors are made nonconductive. In another form, the cascode stage is connected directly to a bit line pair differential signal and to sense nodes ( ) that are separately coupled to a data line pair by a coupler ( ) and an amplifier ( ).
