Abstract: An integrated circuit (IC) structure in a memory device is described. In an example, the IC structure includes a memory cell including a bitline (BL) extending along a first direction and a channel extending along a second direction above and diagonal to the BL. In the example, a wordline (WL) extends in a third direction perpendicular to the first direction of the BL and intersects with the channel to control a current in the channel along a gated channel length. In some examples, the channel is electrically coupled on a first side to a storage capacitor via a storage node contact (SNC) and on a second side to the BL via a bit line contact (BLC) located on an underside or backside of the channel.

Abstract: Embodiments herein describe techniques for a semiconductor device including a substrate oriented in a horizontal direction, and a memory cell including a transistor and a capacitor above the substrate. The transistor includes a gate electrode oriented in a vertical direction substantially orthogonal to the horizontal direction, and a channel layer oriented in the vertical direction, around the gate electrode and separated by a gate dielectric layer from the gate electrode. The capacitor is within an inter-level dielectric layer above the substrate. The capacitor includes a first plate coupled with a second portion of the channel layer of the transistor, and a second plate separated from the first plate by a capacitor dielectric layer. The first plate of the capacitor is also a source electrode of the transistor. Other embodiments may be described and/or claimed.

Abstract: Described herein are embedded dynamic random-access memory (eDRAM) memory cells and arrays, as well as corresponding methods and devices. An exemplary eDRAM memory array implements a memory cell that uses a thin-film transistor (TFT) as a selector transistor. One source/drain (S/D) electrode of the TFT is coupled to a capacitor for storing a memory state of the cell, while the other S/D electrode is coupled to a bitline. The bitline may be a shallow bitline in that a thickness of the bitline may be smaller than a thickness of one or more metal interconnects provided in the same metal layer as the bitline but used for providing electrical connectivity for components outside of the memory array. Such a bitline may be formed in a separate process than said one or more metal interconnects. In an embodiment, the memory cells may be formed in a back end of line process.
