ABSTRACT:
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.
