An improved semiconductor memory apparatus which is capable of an increased data transmission ratio. The apparatus includes a memory array for storing data, a plurality of input/output pads and a data bus connected between data input/output pads for inputting/outputting the data stored in an external element and the memory array data is transferred between the input/output pads and first and second buffers in a time interval manner over basis of width N and between the memory array and the first and second buffer over a bus of width 2N.
