摘要： A power-up signal generator uses a deep power down power-up signal, which should be in a standby state in a deep power down entry, for an initialization of other semiconductor elements in a DRAM device that operates after an internal power supply voltage is generated. The generator also uses the power-up signal, which is disabled in the deep power down entry and enabled in a deep power down exit by the internal power supply voltage. The generator may include a power-up detector for generating a power-up detection signal, a deep power down power-up signal generator for generating a deep power down power-up signal, a power-up signal generator for generating a power-up signal and a power-up controller for determining whether or not to enable the power-up signal in the deep power down entry.

摘要： Disclosed is an input apparatus used in a SSTL interface, which comprises a differential buffer for comparing an external input signal with a reference potential inputted from an external, and a CMOS buffer for buffering the external input signal. In the input apparatus, the CMOS buffer operates when a command signal or an address signal is not inputted from an external, and when a predetermined operation such as a refresh operation is performed, thereby reducing the power consumption in a standby mode. Further, in order to prevent the input apparatus from abnormally operating when the reference potential is not maintained in the normal operation range, a reference potential level detecting circuit is further included in the input apparatus, so that the CMOS buffer operates when the reference potential deviates from a predetermined normal operation range. Furthermore, in order to enable an input buffer to operate as the CMOS when an input signal fully swings, a circuit for detecting a potential of an input signal inputted from an external is further included in the input apparatus.

摘要： A voltage generator for a semiconductor memory device that improves the drivability of an output driver by controlling a gate of the output driver to vary between an internal power supply voltage and a ground voltage, is disclosed. The voltage generator includes an output voltage controller to generate a pull-up signal for controlling a pull-up operation and a pull-down signal for controlling a pull-down operation, the pull-up signal having a level substantially equivalent to an internal power supply voltage if a cell plate voltage is higher than a cell plate reference voltage, and having a level below the cell plate voltage if the cell plate voltage is lower than the cell plate reference voltage. The voltage generator further includes an output driver to generate a stable cell plate voltage in response to the pull-up signal and the pull-down signal.
