    摘要: A control circuit & mode register outputs a signal responsive to each command to a VDC control circuit. The VDC control circuit outputs a signal PWRUP changing the quantity of a through current Ic of a comparator stored in a VDC in response to the command. The VDC control circuit internally generates a signal of which pulse width corresponds to a prescribed delay time, in response to input of the command. Therefore, activation of each bank may not be monitored but current consumption can be reduced by preferably controlling a power supply current while minimizing the number of delay circuits and wires.

    摘要: An internal power supply circuit produces an internal power supply voltage from an external power supply voltage. A voltage level control circuit controls a voltage level and a temperature characteristic of the internal power supply voltage generated by the internal power supply circuit. The internal power supply circuit produces the internal power supply voltage having a negative or zero temperature characteristic in a low temperature region and a positive temperature characteristic in a high temperature region. The voltage level control circuit includes a structure optimizing a capacitance value of a sense power supply line stabilizing capacitance for driving a sense amplifier circuit, a level converting circuit determining the lowest operable region of the external power supply voltage of the internal power supply circuit, or a structure forcedly operating the internal voltage down converter upon power-on. The internal power supply voltage at a desired level is stably produced with a small occupied area and a low current consumption.
