    摘要: A MOS memory device includes an array of rows and columns of memory cells, word lines connected to the rows of memory cells, and a plurality of pairs of bits lines connected to the columns. Sense amplifiers and transfer gates are provided for every bit line pair. A column decoder has outputs connected via column-select lines to transfer gates such that each output is connected to two adjacent gates. When activating a certain column, the column decoder potentially activates another column adjacent to the certain column before actually receiving the corresponding column address. This permits information bits stored in four memory cells to be transferred simultaneously to the registers and latched therein. A multiplexer serially reads out the latched information bits. The column preactivation improves the serial accessing speed of the memory device.

    摘要: A dynamic random-access memory has bit-line pairs, word lines intersecting with the bit-line pairs, and memory cells arranged at the intersections of the bit-line pairs and the word lines, and sense amplifiers provided for the bit-line pairs, respectively. One of every two neighboring bit-line pairs is twisted at one portion, thus forming a twisted crossing section. The twisted crossing section is made of the parts of the gate electrodes of the transistors incorporated in the sense amplifier connected to the twisted bit-line pair. The bit-line pairs is twisted at a portion substantially middle with respect to the direction in which it extends, and the sensr amplifier associated with this bit-line pair is located at the twisted portion thereof.

    摘要: A MOS type random access memory disclosed has a plurality of pairs of sequentially aligned folded type bit lines each of which has a first bit line and a second bit line. Memory cells are arranged at points of intersection between a memory cell word line and the first bit lines. Dummy cells are arranged at points of intersection of a dummy cell word line and the second bit lines. Sense amplifier circuits are connected to the bit line pairs, respectively. In a data read mode of the memory, when a bit data is read from a certain memory cell which is connected to a first word line selected and a first bit line of a selected bit line pair, a second bit line onto which a data voltage is read from a dummy cell of the selected bit line pair is forcedly fixed to a precharge voltage produced by a precharge voltage generator in a presented time interval after the first word line is selected and before a certain sense amplifier circuit connected to the selected bit line pair gets activated, whereby interference noise may be eliminated which is introduced onto the selected bit line pair from a bit line pair adjacent to the selected bit line pair.
