摘要： In a voltage generating circuit for a semiconductor memory device, each of a plurality of reset signal generators individually generates a reset signal in response to one of a plurality of external source voltages. The plurality of external source voltages have different voltage levels. An output voltage generator generates a plurality of output voltages by independently driving each of the plurality of external source voltages in response to a corresponding one of the plurality of reset signals. The output voltage generator outputs the plurality of output voltages through a common output terminal.

摘要： When it is detected that the voltage of a main power supply is reduced below a predetermined value during a normal operation, a power controller switches a power supply for a DRAM from the main power supply to a battery power supply and makes an instruction signal for instruction a self-refresh mode to a memory controller active. In response to this, the memory controller changes a clock enable signal for the DRAM to a low level to establish the self-refresh mode of the DRAM, and, after, the self-refresh mode of the DRAM is established, supplying of power to the memory controller is stopped. The clock enable signal for the DRAM is maintained to the low level by pull-down resistance even when the supplying of power to the memory controller is stopped from a condition that the signal is changed to the low level in the self-refresh mode, thereby maintaining the self-refresh mode of the DRAM.

摘要： A word line boost circuit includes a first pump circuit, a first transistor, a voltage detection circuit and a second pump circuit. The first pump circuit provides a gate boosted signal according to an address transfer detection (ATD) signal. The first transistor has a control terminal for receiving the gate boosted signal and a second terminal coupled to a target word line. The voltage detection circuit is for detecting a voltage level of the gate boosted signal and accordingly outputting a detection signal. The second pump circuit is for outputting a boost signal to a first terminal of the first transistor according to a voltage level of the detection signal. The boost signal boosts the target word line via the turned-on first transistor.

摘要： There is provided a semiconductor device supplied with internal power generated by an internal power generation circuit to perform a stable operation and, also, suppress power consumption. A control circuit, a row/column decoder and a sense amplifier are driven by an internal buck voltage. On the other hand, a data path with high power consumption is driven by an external power supply voltage. A level conversion circuit receives an address signal or a command signal having a voltage level of the external power supply voltage, converts the voltage level to the internal buck voltage, and outputs a resultant signal to the control circuit. A level conversion circuit receives a control signal having a voltage level of the internal buck voltage from the control circuit, converts the voltage level to the external power supply voltage, and outputs a resultant signal to the data path.
