Abstract

A semiconductor memory device includes: a local write bit (LWB) line; a local write bit_bar (LWB_bar) line; a global write bit (GWB) line; a global write bit_bar (GWBL_bar) line; a column of segments, each segment including bit cells; each of the bit cells being coupled correspondingly between the LWB and LWB_bar lines; and a distributed write driving arrangement including local write drivers correspondingly coupled to the segments; and a global write driver coupled to each of the local write drivers.
