Abstract
A single-ended low-swing power-savings mechanism is provided. The mechanism comprises a precharge device that turns off in an evaluation phase and a first biasing device is always on. Within the mechanism, a strength of a keeper device is changed to a first level in response to an input of the second biasing device being at a first voltage level. Within the mechanism the strength of the keeper device is changed to a second level in response to the input of the second biasing device being at a second voltage level. Responsive to receiving a (precharged voltage level read data line signal, a precharged voltage level of the first node falls faster when the keeper device is weakened to a first level. The keeper device turns on in response to receiving a LOW signal and pulls up the voltage at the first node so that a HIGH signal is output.
