Abstract
A sense amplifier circuit includes a power node having a power node voltage at a power voltage level, a bit line having a bit line voltage, a sense amplifier output, an NMOS transistor and a PMOS transistor coupled in series between the power node and the bit line, and a logic gate configured to generate a sense amplifier output voltage at the sense amplifier output based on the bit line voltage. The NMOS transistor is configured to operate in a sub-threshold region to maintain the bit line voltage at a first level and operate in a region above the sub-threshold region to maintain the bit line voltage at a second level, and the first level is between the second level and the power voltage level.
