ABSTRACT:
A semiconductor integrated circuit device permitting the chip area to be as small as possible without lowering the maximum arrival voltage is provided. This semiconductor integrated circuit device includes first to n-th charge pump circuits respectively driven on the basis of clocks CLK1, CLK2 to bias semiconductor substrate or well formed at the semiconductor substrate, wherein the i-th (i=1, . . . n-1) charge pump circuit is caused to be of a structure in which the current drivability is large, but the maximum arrival voltage is low as compared to the (i+1)-th charge pump circuit.
