Abstract
A semiconductor memory device (20) includes N bitlines (31, 32, 33, 34) addressable by a partially decoded column address, wherein N is greater two. A column address selection lead (YSEL) has plural segments, each of which overlays a length of one of the bitlines. Each segment of the column address selection lead overlays no more than approximately 1/N of the length of a bitline. Adjacent column address selection leads are separated by approximately the pitch of N-1 bitlines.
