Abstract

A voltage generating circuit 100 of the present invention includes a control logic 110, a voltage generating element 120 and a connecting element 130. The voltage generating element 120 includes a plurality of registers A-1, B-1, C-1, D-1, voltage generating blocks A-2, B-2, C-2 and a voltage switch 32. The registers A-1, B-1, C-1, D-1 hold data provided from control logic 110. The voltage generating blocks A-2, B-2, C-2 generate voltage based on voltage control data held by the registers A-1, B-1, C-1. The voltage switch 32 selects voltages based on selection control data held by the register D-1. The connecting element 130 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.
