ABSTRACT:
A sense amplifier has a pair of output terminals and a first pair of pull-up transistors. A second pair of transistors is connected between the output terminals and a pull-down node. The gate electrodes of the second pair are cross-coupled to the output terminals. A third pair of transistors is connected between the output terminals and the pull-down node and have gate electrodes coupled to input potentials. A fourth pair of transistors is connected between the output terminals and the pull-down node and also have gate electrodes coupled to input potentials.
