ABSTRACT:
The present invention describes a circuit and method for utilizing a single dummy cell for each sense amplifier in a dynamic random access memory (DRAM) device. A precharge transistor connects a dummy cell capacitor to a reference potential and decoded selection transistors. The use of decoded selection transistors provides a means to share the dummy cell capacitor between either input of a differential or sense amplifier thereby reducing required area and circuit complexity.
