Abstract
A sense amplifier enable signal generating circuit includes a dummy bit cell which is connected to a dummy word line and a dummy bit line and discharges the dummy bit line in response to a signal level of the dummy word line. The sense amplifier enable signal generating circuit further comprises a process tracking circuit which adjusts a signal level of the dummy word line in response to a signal level of the dummy bit line to adjust a discharge rate of the dummy bit line, and a sense amplifier control circuit that generates the sense amplifier enable signal responsive to the signal level of the dummy bit line. In further embodiments, the sense amplifier control circuit includes a control circuit that generates the sense amplifier enable signal responsive to an internal clock signal and a control signal. A process adjusting circuit is connected to the dummy bit line and generates the control signal responsive to a signal level on the dummy bit line and the internal clock signal.
