    摘要: A device includes an active region formed of a semiconductor material, a gate dielectric at a surface of the active region, and a gate electrode over the gate dielectric. A first source/drain region and a second source/drain region are on opposite sides of the gate electrode. A Contact Etch Stop Layer (CESL) is over the first and the second source/drain regions. An Inter-Layer Dielectric (ILD) includes a top surface substantially level with a top surface of the gate electrode. A first contact plug is over and electrically connected to the first source/drain region. A second contact plug is over and aligned to the second source/drain region. The second contact plug and the second source/drain region are spaced apart from each other by a portion of the first CESL to form a capacitor.

    摘要: In some embodiments related to a memory array, a sense amplifier (SA) uses a first power supply, e.g., voltage VDDA, while other circuitry, e.g., signal output logic, uses a second power supply, e.g., voltage VDDB. Various embodiments place the SA and a pair of transferring devices at a local IO row, and a voltage keeper at the main IO section of the same memory array. The SA, the transferring devices, and the voltage keeper, when appropriate, operate together so that the data logic of the circuitry provided by voltage VDDB is the same as the data logic of the circuitry provided by voltage VDDA.
