Abstract
PURPOSE:To convert the titled memory to a small area by curtailing the number of word lines and bit lines. CONSTITUTION:It is executed (c) times successively to input simultaneously (p) pieces of word line address signals WAa1-WAap to a word line selection driving device WSDa, and in accordance therewith, word line address signal holding control signals WAHSa1-WAHSap are outputted simultaneously from a control signal generating device, and word line selection use control signals WSSa1-WSSap are outputted repeatedly (q) times successively to the word line selection driving device WSDa. Also, a bit line selection use control signal BSSa and information detection/amplification use control signals IDSa1-IDSap, and information output use control signals IOSa1-IOSap are outputted repeatedly (q) times successively to an information reader IRa. Accordingly, (p) pieces of memory cell information can be outputted simultaneously (q) times to (p) pieces of information output lines ITa1-ITap. In such a way, the titled memory can be miniaturized.
