Abstract

A semiconductor device including a voltage generation circuit, and voltage generation circuit generates a required voltage according to internal data requested in response to an operation are provided. The voltage generating circuit includes a plurality of registers A-, B-, C-, D-, voltage generating blocks A-, B-, C-and a voltage switch. The registers A-, B-, C-, D-hold data provided from control logic. The voltage generating blocks A-, B-, C-generate voltage based on voltage control data held by the registers A-, B-, C-. The voltage switch selects voltages based on selection control data held by the register D-. The connecting element includes signal lines for sequentially transmitting the voltage control data or the selection control data, signal lines for sequentially transmitting a clock signal CLK and signal lines for controlling output of data held by the registers.
