Abstract
A row address decoder and word line driver unit selectively drives a word line selected from one of a plurality sets of word lines, and comprises a plurality of row address decoders and word line driver sub-units for selecting a set of word lines and a plurality of address decoder sub-units for selecting a word line from the selected set of word lines, wherein a pair of p-channel enhancement type transfer transistors coupled between a selected row address decoder and word line driver unit and the selected word line are switched by a selected address decoder sub-unit for supplying a word line driving signal, the complementary word line driving signal switches an n-channel enhancement type first pull-down transistor coupled between the selected word line and a ground voltage line, and the selected address decoder sub-unit further switches an n-channel enhancement type second pull-down transistor, thereby charging to and discharging from the selected word line through the transistors operable in the saturation region.
