Abstract
A semiconductor memory device includes different types of memory matrices adjacently arranged such that bit lines are aligned in the same cell matrix region, a column decoder for selecting the bit lines of the memory matrix, and a row decoder for selecting the row lines of the memory matrix. Therefore, a semiconductor memory device having many types of memory matrices can be highly integrated in the same cell matrix region in the same layout.
