Abstract
A dynamic random access memory is formed with two power supply meshes extending throughout a memory array region in which are formed memory cells and sense amplifier circuits, thereby enabling sense amplifier drive circuits to be distributed throughout that memory array region, with each sense amplifier drive circuit being connected to the nearest points on the two supply meshes. A substantially improved value of read access time, or increased total memory capacity, can thereby be achieved by comparison with a DRAM in which the sense amplifier drive circuits are provided only at the periphery of a memory array region.
