Abstract
A sense amplifier control system includes a precharge control switch configured to receive a precharge signal. A reference cell is configured to receive a reference word line signal. In a precharge phase, the control switch is controlled in response to the precharge signal to precharge the reference input node to a predetermined precharge level. In a sensing phase subsequent to the pre-charge phase, the trigger circuit is configured to output a triggering signal at the output terminal in response to the reference input node reaching a triggering level.
