Abstract
A sense amplifier circuit includes a sense amplifier, a switch and a temperature compensation circuit. The temperature compensation circuit provides a control signal having a positive temperature coefficient, based on which the switch provides reference impedance for temperature compensation. The sense amplifier includes a first input end coupled to a target bit and a second input end coupled to the switch. The sense amplifier outputs a sense amplifier signal based on the reference impedance and the impedance of the target bit.
