Abstract
A dynamic random access memory (DRAM) is provided and includes a base substrate. The base substrate includes a semiconductor substrate, a plurality of fins formed on the semiconductor substrate, and an isolation structure formed on the semiconductor substrate and covering portions of side surfaces of the plurality of fins. The dynamic random access memory further includes an interlayer dielectric layer formed over the base substrate and covering top surfaces of the plurality of fins and the isolation structure; and a memory structure, formed in an opening passing through the interlayer dielectric layer and each of the plurality of fins, the opening extending to and exposing a top surface of a portion of the isolation structure. The memory structure includes a first conductive layer, a memory medium layer on the first conductive layer, and a second conductive layer on the memory medium layer.
