Abstract:
A sense amplifier is provided that comprises, responsive to receiving a set signal to turn on a set device and a precharged voltage level read bit line signal, a keeper device that turns on responsive to receiving a LOW signal from an inverting amplifier and pulls up the voltage at a first node so that a HIGH signal is output onto a global bit line. Responsive to receiving the set signal to turn on the set device and a read bit line signal that is discharging through a read stack path to ground and responsive to the read bit line signal discharging below a first predesigned voltage level, a read assist device in the sense amplifier turns on responsive to receiving a HIGH signal from the inverting amplifier and pulls down the voltage at the first node so that a LOW state is output onto a global bit line.
