Abstract
PURPOSE:To speed up a writing operation only for the time of reading operation, by executing the writing operation without accompanying the reading operation when data are transferred from a serial access memory. CONSTITUTION:When the data are written to a dynamic memory 1 in which a memory cell is arranged in a matrix shape and all the memory cells of the arbitrary line of the dynamic memory 1 having a serial access memory 2 connected to the input side of the dynamic memory 1, data from the serial access memory 2 are outputted to a bit line simultaneously with the selecting operation of a word line to correspond to the arbitrary line or preceding to the selecting operation. Then, the writing of the data is executed without accompanying the reading of the data from the respective memory cells. When the data are written to all the memory cells of the arbitrary line, it is eliminated to read the data in advance since all the data of the line are updated. Accordingly, by executing the writing of the data without accompanying the reading of the data, high speed can be realized only by a part in which the reading operation is eliminated.
