  • Patent number: 9418713
    Abstract: A sense amplifier includes four sub-circuits: pre-charge, sense enable, sense output, and buffer. The pre-charge sub-circuit provides a voltage between zero volts and the positive power supply (denoted VDD) to the sense enable sub-circuit. The sense enable sub-circuit is configured to adjust the received voltage based on the sensed value of bit lines and sends the adjusted voltage to the sense output sub-circuit. The sense output sub-circuit removes interference, inverts and amplifies the adjusted voltage, and sends an output voltage to the buffer sub-circuit. The buffer sub-circuit amplifies the output voltage of the sense output sub-circuit and provides it to an output bus.
