    摘要: Described herein are ferroelectric (FE) memory cells that include transistors having gates with FE capacitors integrated therein. An example memory cell includes a transistor having a semiconductor channel material, a gate dielectric over the semiconductor material, a first conductor material over the gate dielectric, a FE material over the first conductor material, and a second conductor material over the FE material. The first and second conductor materials form, respectively, first and second capacitor electrodes of a capacitor, where the first and second capacitor electrodes are separated by the FE material (hence, a “FE capacitor”). Separating a FE material from a semiconductor channel material of a transistor with a layer of a gate dielectric and a layer of a first conductor material eliminates the FE-semiconductor interface that may cause endurance issues in some other FE memory cells.

    摘要: Embodiments herein describe techniques for an integrated circuit (IC). The IC may include a capacitor. The capacitor may include a first electrode, a second electrode, and a paraelectric layer between the first electrode and the second electrode. A first interface with a first work function exists between the paraelectric layer and the first electrode. A second interface with a second work function exists between the paraelectric layer and the second electrode. The paraelectric layer may include a ferroelectric material or an anti-ferroelectric material. A built-in electric field associated with the first work function and the second work function may exist between the first electrode and the second electrode. The built-in electric field may be at a voltage value where the capacitor may operate at a center of a memory window of a polarization-voltage hysteresis loop of the capacitor. Other embodiments may be described and/or claimed.

    摘要: Described is an apparatus which comprises: a first access transistor controllable by a write word-line (WWL); a second access transistor controllable by a read word-line (RWL); and a ferroelectric cell coupled to the first and second access transistors, wherein the ferroelectric cell is programmable via the WWL and readable via the RWL. Described is a method which comprises: driving a WWL, coupled to a gate terminal of a first access transistor, to cause the first access transistor to turn on; and driving a WBL coupled to a source/drain terminal of the first access transistor, the driven WBL to charge or discharge a storage node coupled to the first access transistor when the first access transistor is turned on, wherein the ferroelectric cell is coupled to the storage node and programmable according to the charged or discharged storage node.
