Abstract
A semiconductor memory device is improved as regards current consumption and access time by dividing the memory cells into a plurality of columner groups and providing group selecting lines. Front-end word lines of low resistance are connected to outputs of row decoders, and AND gates receive selecting signals on the group selecting lines and the outputs of the front-end word lines. Word lines of a comparatively short length are connected to the AND outputs.
