PURPOSE:To read memeory cells arranged in a matrix simultaneously by selecting one of two data lines, assigned by two selection lines assigned to every memory cell, correspondingly. CONSTITUTION:To each memory cell 10 in a matrix array, two selection lines COL and two data lines BUS are assigned, and the lines COL control selective connections between the corresponding lines BUS and the cell 10. This constitution enables data of the memory cell at difference address positions to be read simultaneously, thereby realizing a storage circuit device which is accessible at a high speed. |
