ABSTRACT:
The present invention relates to the improvement in the degree of on-chip integration of memory cells utilizing a gate array layout. A plurality of three-transistor DRAM cells are disposed on a semiconductor chip implementing a regular cross-point array, each DRAM cell is made up of two nMOS transistors and one pMOS transistor formed in one basic cell. The semiconductor chip disposes therein nMOS memory-cell blocks and pMOS memory-cell blocks alternately, effectively utilizing the gate array layout.
