Abstract
PURPOSE:To accurately constitute a small-sized titled memory by reducing the word lines and the bit lines of a memory cell array. CONSTITUTION:The plural (p) pieces of word line address signals WAa1-WAap are inputted to a word line selecting driving device, bit line address signals BAa1-BAap are inputted to a control signal generating device CSa and the word line address signals WAa1-WAap and the bit line signals BAa1-BAap are inputted to a control signal generating device CCa successively with number of times (q). Control signals WGSa1, WGSa2...WGSap for a word line decoding output gate are successively outputted from the control signal generating device CCa to a word line selecting driving device WSDa, control signals BGSa1, BGSa2-BGSap for a bit line selection are successively outputted to the control signal generating device CSa and control signals IDOSa1, IDOSa2...IDOSap for an information detection/amplification are successively outputted to an information reader with number of times (q). Thus, the miniaturization of the memory is attained accurately.
