Memory array architecture, method of operating a dynamic random access memory, and method of manufacturing a dynamic random access memory

摘要

A dynamic random access memory includes a plate line; a digit line; a memory cell selectively coupled between the digit line and the plate line; sense circuitry selectively coupled to the memory cell to read the memory cell and capable of applying a first voltage from the plate line to the digit line; equilibration circuitry selectively coupling the plate line to an equilibration voltage less than the first voltage and selectively coupling the digit line to the equilibration voltage; and control circuitry configured to cause the equilibration circuitry to couple the plate line to the equilibration voltage while the memory cell is being accessed. A method of manufacturing a dynamic random access memory includes providing control circuitry configured to operate in a specified manner. A method of operating a dynamic random access memory includes turning on one equilibration transistor, while another equilibration transistor is off, so that a plate line equilibrates to a voltage defined by the equilibration voltage source during accessing of a memory cell.
