CIRCUIT FOR GENERATING SENSE AMPLIFIER ENABLE SIGNAL COMPRISING PROCESSOR TRACKING CIRCUIT AND SEMICONDUCTOR MEMORY DEVICE COMPRISING THE SAME

摘要

PURPOSE: A circuit for generating a sense amplifier enable signal comprising a processor tracking circuit and a semiconductor memory device comprising the same are provided to minimize difference between the delay characteristics of a path for data sensing and delay characteristics of a path for generating a sense amplifier enable signal even though there is a process change. CONSTITUTION: According to the circuit(300) for generating a sense amplifier enable signal of a semiconductor memory device generating a signal enabling a bit line sense amplifier, a dummy bit cell(22) is connected to a dummy word line and a dummy bit line and discharges the dummy bit line in response to a signal of the dummy word line. And a processor tracking circuit(21) adjusts a signal level of the dummy word line in response to a signal level of the dummy bit line to adjust a discharge speed of the dummy bit line.
