Abstract
A semiconductor memory device includes a plurality of regions. Each region includes memory cell arrays, an input/output circuit zone, column decoders, and a row decoder. The input/output circuit zone is placed between the memory cell arrays. The input/output circuit zone inputs or outputs data to or from the memory cell arrays selectively. As a result, high integration is realized with ease.
