ABSTRACT:
The semiconductor memory device is improved so as to be simplified and to cope with a high speed CPU by allowing the CPU and the memory device to be controllable by only a single clock. The address control sections are operated on the basis of a monoperiod clock signal CLK and a group of control signals. The column address is applied to a plurality of divided memory cell arrays, respectively, so that the memory cell arrays can be interleaved with each other. The input and output buffers controlled by the input and output control section 1 are operated in pipeline processing, to increase the access speed of data read from or written in the memory cell arrays 17 and 18.
