Abstract
A circuit includes a bit line, a pass gate coupled between the bit line and a power node having a first power voltage level, and a driver coupled between the bit line and a reference node having a reference voltage level. The pass gate couples the bit line to the power node when the first signal has the reference voltage level and decouples the bit line from the power node when the first signal has the first power voltage level. The driver receives a second signal based on a control signal, couples the bit line to the reference node when the second signal has a second power voltage level below the first power voltage level, and decouples the bit line from the reference node when the second signal has the reference voltage level. An input circuit generates the first signal independent of the control signal.
