Abstract:
1. A method of reducing coupling noise between adjacent wordlines in a memory device comprising: selecting a first wordline; delivering an enable signal from a first row decoder to a first wordline driver, wherein the first wordline driver is configured to drive the first wordline; and delivering a disable signal from a second row decoder to a second wordline driver, wherein the second wordline driver is configured to drive a second wordline, and wherein the second wordline is immediately adjacent to the first wordline; delivering both an enable signal from the first row decoder and a phase signal from a phase driver to a third wordline driver, wherein the third wordline driver is configured to drive a third wordline, and wherein the third wordline driver is further configured to sink coupling noise on the third wordline to ground upon receiving the phase signal, the third wordline driver being immediately adjacent to a first side of the second wordline driver receiving the disable signal from the second row decoder, the third wordline being immediately adjacent to the second wordline; and wherein the first wordline driver is immediately adjacent to a second side of the second wordline driver, the first and second sides of the second wordline driver being opposite from one another.
