Abstract
A method of maintaining a voltage level of a bit line of a sense amplifier circuit includes providing a power supply voltage at a power supply node, receiving the power supply voltage from the power supply node with an NMOS transistor, and maintaining a voltage level of the bit line by supplying sufficient current with the NMOS transistor to compensate a leakage current of the bit line. The method includes receiving the voltage level of the bit line with a noise threshold control circuit, inverting the voltage level with the noise threshold control circuit, and driving a sense amplifier output with the noise threshold control circuit.
