WORD-LINE DRIVER ARRAY METHOD OF SEMICONDUCTOR MEMORY DEVICE

摘要

A memory cell array comprises a memory matrix including memory cells, word lines and bit lines, word line drivers and row address decoders. The arranging method comprises partitioning the word line drivers into a number of word line driver groups and staggering the word line driver groups to allow denser packing of the memory cell array since larger chip area is provided for each word line driver. In increasing the pitch of the word line drivers, increased design margins may be allowed in the layout of the memory device.
