ABSTRACT:
Provided are a semiconductor device having a sense amplifier driver and a method of generating a sense amplifier enable signal for enabling a sense amplifier. The semiconductor device includes a sense amplifier, which is comprised of a plurality of inverters which are connected in series, a power supply circuit, and a discharge circuit. In this semiconductor device, an enabling timing of the sense amplifier enable signal is controlled by delaying a time taken to evaluate a first dummy bit line from a power supply voltage to a ground voltage using parasitic capacitance between the first dummy bit line and a first complementary dummy bit line. The method of generating the sense amplifier enable signal is performed using the above-described sense amplifier.
