    Abstract: PROBLEM TO BE SOLVED: To make generable a reference voltage in a comparatively short time by a method wherein a first switching element which is used to connect two bit lines and a selection transistor for two reference memory cells are turned on, only the selection transistor is turned off after a prescribed period, and the potential difference between the two bit lines is offset. SOLUTION: A first switching element S1 which short-circuits a first and second bit lines BL1 and the inverse of BL1, and a selection transistor for two reference memory cells RCs are turned on by a control unit C1. After a prescribed period has elaped, the first switching element S1 is continuously set to continuity, and the potential difference between the bit lines BL1 and the inverse of BL1 is offset. Consequently, the influence of the nonlinear memory capacitor of the reference memory cells RCs on a reference voltage is smaller than that, in a case where the selection transistor is set to continuity up to the perfect equilibrium of an electric charge between the bit lines BL1 and the inverse of BL1.

    Abstract: An integrated memory in which the plate lines run parallel to the bit lines and are driven by the column decoder. The effect achieved by the fact that each plate line is connected to the memory cells of the associated bit line is that only those memory cells whose associated bit line is required for the respective memory access are affected by the pulsed signals of the plate line. Therefore, only the potential of that bit line which is currently required for a data transfer is influenced by pulsed signals on the associated plate lines.
