    摘要: The bit-line sense amplifier includes a driving-voltage control circuit and an amplifier. The driving-voltage control circuit generates a first test driving voltage having a voltage level of a pre-charge voltage, a second test driving voltage having a voltage level of a pre-charge voltage added by a voltage difference between a bit-line and a complementary bit-line, and a third test driving voltage having a voltage level of a pre-charge voltage subtracted by the voltage difference in a test mode. The amplifier senses and amplifies a voltage difference between the bit-line and the complementary bit-line.

    摘要: Provided is a semiconductor memory device including a sub-word-line driving circuit capable of reducing an amount of leakage current due to coupling. The semiconductor memory device includes a word-line enable signal generating circuit and a sub-word-line driving circuit. The sub-word-line driving circuit provides a pull-down current path between a selected word line and ground for a pulse type period of time in a precharge mode following an active mode for the selected word line, generates a word line driving signal on the basis of a main word line driving signal, a first sub-word-line control signal, and a second sub-word-line control signal, and provides the word line driving signal to a memory cell array. The semiconductor memory device may reduce an amount of leakage current flowing to a ground through the sub-word-line driving circuit.

    摘要: An internal voltage generating circuit of a semiconductor memory device includes a driving current generator that controls the magnitude of a driving current and supplies a controlled driving current in response to signals activated according to an operational mode. A comparison voltage generator receives a reference voltage and an internal power supply voltage, outputs a differentially amplified comparison voltage in response to a voltage difference between the reference voltage and the internal power supply voltage, and operates according to the driving current. A bulk bias controller receives at least two voltages and selectively outputs a voltage as a bulk bias voltage in response to a power-down enable signal, a normal enable signal, and an operating enable signal. An internal voltage driver controls a threshold voltage in response to the bulk bias voltage, controls a current amount in response to the comparison voltage, and outputs the internal power supply voltage.
