Memory devices include a semiconductor substrate and a device isolation layer in the substrate and defining a cell region and a resistance region. A resistance pattern is disposed on the device isolation layer in the resistance region. An interlayer insulating layer is on the resistance pattern and a resistance contact hole with a contact plug therein extends through the interlayer insulating layer and exposes the resistance pattern. A conductive pad pattern is interposed between the resistance pattern and the device isolation layer that is electrically connected to the resistance pattern. The conductive pad pattern is positioned between the resistance contact hole and the device isolation layer and has a planar area greater than a planar area of the resistance pattern exposed by the resistance contact hole. The conductive pad pattern and the resistance pattern define a resistor of the memory device having a greater thickness in a region including the conductive pad pattern.

A semiconductor device includes a substrate having a cell region and a connection region. A plurality of gate electrodes is stacked in a vertical direction in the cell region of the substrate. Conductive pads that are electrically connected to a peripheral circuit extend horizontally from the gate electrodes to the connection region. The conductive pads form a cascade structure in the connection region. Contact plugs that have different vertical lengths are electrically connected to respective ones of the conductive pads. The conductive pads have contact portions that are thicker in the vertical direction than the gate electrodes.
