Abstract:
A method of routing signals within a semiconductor memory device includes providing a semiconductor wafer having a top surface with a center portion, an edge portion and wafer bond pads at the center portion. A redistribution layer is provided on the top surface of the semiconductor wafer. The method includes redistributing signals from the wafer bond pads to redistribution edge pads utilizing the redistribution layer, and routing signals from the semiconductor wafer up to the redistribution layer and routing these signals back down to the semiconductor wafer.
