Abstract
An apparatus (and method) is provided that reduces noise in an embedded DRAM caused by noise in the Vdd supply. A circuit switches or decouples the bit line precharge voltage supply from the memory array to reduce noise in the memory array at time of bit line sensing. In addition, another circuit is utilized to switch or decouple the memory cell plate voltage supply from the memory array to reduce noise in the memory array at the time of bit line sensing. The circuit(s) includes a switch to perform the decoupling, or alternatively, include a switch coupled in parallel with a high impedance.
