Abstract
A semiconductor device of a memory-macro type can be designed within a short time to have a desired storage capacity, which does not occupy a large area, so as to reduce the chip cost. The semiconductor device includes a memory macro having sub-memory macros, each sub-memory macro having a DRAM memory-cell array, and a row decoder and a column decoder for selecting any desired memory-cell from the memory cell of the array. The memory macro also includes a control-section macro having a DC potential generating circuit for generating various DC potentials required to drive the sub-memory macros. At least one of the sub-memory macros is combined with the control-section macro to form the memory macro as a one-chip memory capable of storing an integral multiple of N bits.
