Abstract
A sense amplifier circuit includes: a data line; a sense amplifier output node; a keeper circuit; a logic gate; a noise threshold circuit; and an inverter. The keeper circuit includes a first transistor and a second transistor connected in series and coupled between a first power node and the data line. A gate node of the first transistor is coupled to the sense amplifier output node. The logic gate has an input connected to the bit line and an output connected to the sense amplifier output node. The noise threshold circuit includes: a third transistor and a fourth transistor connected in series between a second power node and the sense amplifier output node; and an inverter connected between a gate node of the third transistor and the sense amplifier output node.
