ABSTRACT:
A semiconductor memory device adapted to enhanced functional features and a large memory capacity. The semiconductor memory device includes a semiconductor chip divided into 9 regions B1 through B9 having an identical area, in a 3.times.3 pattern. A main control block is arranged at least in a central region B9 and memory blocks are arranged respectively in the peripheral regions B1 through B8 of the 9 regions. Each of the memory blocks is controlled by the main control block and includes a data input/output circuit and a memory control circuit.
