A block selection circuit and a semiconductor device having the same may include a row decoder which includes a high voltage generating circuit configured to output a block selection voltage in response to upper addresses, switching circuits configured to receive the block selection voltage and a precharge high voltage, and forward the block selection voltage through one of the switching circuits that is selected in response to selection signals, and pass transistor groups configured to select a memory block in response to the forwarded block selection voltage.

Block selection circuit and semiconductor device having the same

A pumping circuit includes a cross-coupled charge pump circuit including first and second capacitors configured to pump an input voltage in response to a first clock signal and to an inverted first clock signal and a plurality of transistors configured to one of transfer the input voltage to the first and second capacitors and to transfer a pumping voltage to an output node, and a switching voltage supply circuit configured to supply switching voltages to gates of the plurality of transistors to enable the transfer of the input voltage and the pumping voltage.

Pumping circuit

A regulator includes an input voltage adjusting unit configured to adjust a pumping voltage in response to a control signal varied depending on a target voltage and output the adjusted pumping voltage and a regulation unit configured to output the target voltage by regulating the adjusted pumping voltage. The regulator may reduce current consumption by adjusting the pumping voltage inputted according to the target voltage.
