Abstract:
1. A method of making a non-volatile memory device, comprising: providing a substrate having a substrate surface; and forming a non-volatile memory array over the substrate surface; wherein: the non-volatile memory array comprises an array of semiconductor diodes; each semiconductor diode of the array of semiconductor diodes is disposed substantially parallel to the substrate surface; each semiconductor diode is disposed horizontally with respect to the substrate surface; in each semiconductor diode, a p-type semiconductor region and an n-type semiconductor region are equidistant from the substrate surface; the step of forming the non-volatile memory array comprises monolithically forming a plurality of device levels of the semiconductor diodes such that the plurality of device levels are stacked in a vertical direction with respect to the substrate surface; and the step of forming the non-volatile memory array further comprises:
