Abstract
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.
