Abstract
A sense amplifier wherein each of a first through a fourth inverter comprises a driving transistor and a load transistor; the first, second, third and fourth inverters are interconnected in such a way that the outputs of the first and second inverters are applied to the third and fourth inverters, respectively; the first and second inverters have input terminals while the third and fourth inverters have output terminals; one terminal of each of the first through fourth inverters is connected to first power supply while the other terminals of the first and second inverters are connected directly or through a control transistor to second power supply; and the outputs from the first and second inverters are applied to the other terminals of third and fourth inverter, respectively.
