  • Patent number: 11854970
    Abstract: Circuit devices, such as integrated circuit devices, are constructed with combination circuits that include two or more cascading transistors, and one or more metal layers disposed over the cascading transistors. The cascading transistors include multiple internal nodes (e.g., common source/drain regions). The multiple internal nodes are not connected to a common metal stripe (the same metal stripe) in the one or more metal layers. The absence of the connections between the internal nodes and a common metal stripe reduce or eliminate the load on the internal nodes. The transistors in the cascading transistors are independent of each other.

  • Patent number: 11790958
    Abstract: A method of operating a memory device is provided. A clock signal is received. Each clock cycle of the clock signal initiates a write operation or a read operation in a memory device. A power nap period is then determined. The power nap period is compared with a clock cycle period to determine that the power nap period is less than the clock cycle period of the clock signal. A header control signal is generated in response to determining that the power nap period is less than the clock cycle period. The header control signal turns off a header of a component of the memory device.

  • Patent number: 11675505
    Abstract: Various embodiments for configurable memory storage systems are disclosed. The configurable memory storages selectively choose an operational voltage signal from among multiple voltage signals to dynamically control various operational parameters. For example, the configurable memory storages selectively choose a maximum voltage signal from among the multiple voltage signals to maximize read/write speed. As another example, the configurable memory storages selectively choose a minimum voltage signal from among the multiple voltage signals to minimize power consumption.

  • Publication number: 20220359279
    Abstract: Embodiments herein are generally directed to methods of forming high aspect ratio metal contacts and/or interconnect features, e.g., tungsten features, in a semiconductor device. Often, conformal deposition of tungsten in a high aspect ratio opening results in a seam and/or void where the outward growth of tungsten from one or more walls of the opening meet. Thus, the methods set forth herein provide for a desirable bottom up tungsten bulk fill to avoid the formation of seams and/or voids in the resulting interconnect features, and provide an improved contact metal structure and method of forming the same. In some embodiments, an improved overburden layer or overburden layer structure is formed over the field region of the substrate to enable the formation of a contact or interconnect structure that has improved characteristics over conventionally formed contacts or interconnect structures.
