摘要： The present invention provides a semiconductor device and a control method thereof, the semiconductor device including: a bit line connected to a memory cell; a voltage control circuit controlling a voltage supplied from a voltage source to the bit line; a differential amplifier circuit providing the control voltage to the voltage control circuit in response to a voltage at a node coupled to the bit line and a reference voltage; and a current source providing a current to the differential amplifier circuit. The current source provides more current to the differential amplifier circuit in the first period including a period for precharging than in the second period after precharging.

摘要： A low-dropout regulator with a single-transistor-control providing improved transient response and stability is disclosed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a sufficiently high frequency without affecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substantially relaxed.
