Abstract
An integrated circuit structure includes a substrate, an interconnect stack, a first memory array, and a source line. The interconnect stack is over the substrate. The first memory array is over the interconnect stack and includes memory elements stacked in a vertical direction each comprising a conductive layer. The first memory array further includes a memory layer electrically connecting to the conductive layers of the memory elements and extending downwardly from a topmost one of the conductive layers to a lowermost one of the conductive layers; and a channel layer extending along a sidewall of the memory layer. The source line is in contact with a top end of the channel layer and laterally extends across the first memory array.
