Semiconductor device having sense amplifier driver capable of controlling enabling timing and method for generating enable-signal for the sense amplifier

摘要

The method for generating a sense amplifier enable signal for enabling the sense amplifier, and a semiconductor device is disclosed that includes a sense amplifier driver. A plurality of inverters connected in series, the semiconductor device having a sense amplifier, which is implemented as a power supply circuit and the discharge circuit by the parasitic capacitance and the off current is formed between the first dummy bit line with the first complementary dummy bit lines by using the voltage of the second dummy bit line to a voltage drop occurs a delay time of the first dummy bit line is that this valuation to the ground voltage in the power supply voltage and controls the activation timing of the sense amplifier enable signal. The sense amplifier enable signal generating method is implemented by the amplifier Kim Ji. ; The sense amplifier driver, sense amplifier
