摘要： A dynamic RAM is provided with a main word lines; a plurality of subsidiary word lines which are arranged in the direction of bit lines crossing the main word line and to which a plurality of dynamic memory cells are connected; a plurality of subsidiary word selection lines which are extended so as to perpendicularly intersect the main word line and through which a selection signal for selecting one of the plurality of subsidiary word lines is transmitted; and a logic circuit for receiving a selection signal from the main word line and a selection signal from each of the subsidiary word selection lines to thereby form a selection signal for selecting one of the subsidiary word lines. In the dynamic RAM, the voltage level of each of the main word line and the subsidiary word selection lines is made to be equal to the ground potential when the line is in a not-selected state.

摘要： Providing a semiconductor device which lessen influence of the transistor threshold voltage deviation that is one of noise elements when the sense amplifiers are amplified, and which are capable of accurately sensing and amplifying micro signals having read from the memory cells in the sense amplifiers. In a DRAM chip, P+-type gate PMOSs of P+-type polysilicon gates each having a low impurity density of channel and N+-type gate NMOSs of N+-type polysilicon gates are used in a sense amplifier cross coupling section to further increase substrate voltages of the PMOSs and to decrease substrate voltages of the NMOS. For this reason, a deviation of threshold voltage caused by channel implantation is reduced, and a small signal generated on a data line at a read operation of a low-potential memory array is accurately sensed and amplified by a sense amplifier. In addition, the threshold voltages are increased by a substrate bias effect, and a leakage current in a sense amplifier data holding state is reduced.

摘要： A dynamic RAM is provided using a sense amplifier compensating for the disparities of characteristics for paired MOSFET's. With this arrangement parasitic capacitance of the bit lines can be increased to be at least 20 times the capacitance of the memory cells. Each bit line is bisected by a switch MOSFET and is disconnected thereby as needed. A plurality of sets of memory arrays are furnished, each including a switch MOSFET for interconnecting common source lines to which the sense amplifier is connected. This permits recycling of the charges of the common source lines.
