ABSTRACT:
A memory device is described which uses dynamic digitline sensing where separate plate lines are provided for each digitline of a memory cell array. A voltage of the plate line is dynamic in that it changes during read operations to create a larger differential for sensing stored data. A method is described which uses either an inactive digitline or a simulation circuit to perform an equilibration operation. Thus, the memory uses an inactive digitline for equilibration which is not necessary for data sensing.
