    摘要: In one embodiment, a memory cell circuit for storing data includes a pair of cross-coupled inverters for storing states of the memory cell circuit. Access devices provide access to the pair of cross-coupled inverters. The memory cell circuit also includes a set of electrically inactive p-type metal oxide semiconductor (PMOS) devices that are coupled to the pair of cross-coupled inverters. The set of electrically inactive PMOS devices in combination with a portion (e.g., PMOS devices) of the pair of cross-coupled inverters enables a continuous p-type diffusion layer for the memory cell circuit.

    摘要: Interconnect fuse structures including a fuse with a necked line segment, as well as methods of fabricating such structures. A current driven by an applied fuse programming voltage may open necked fuse segments to affect operation of an IC. In embodiments, the fuse structure includes a pair of neighboring interconnect lines equidistant from a center interconnect line. In further embodiments, the center interconnect line, and at least one of the neighboring interconnect lines, include line segments of lateral widths that differ by a same, and complementary amount. In further embodiments, the center interconnect line is interconnected at opposite ends of a necked line segment. In further embodiments, the necked line segment is fabricated with pitch-reducing spacer-based patterning process.

    摘要: A method for bi-directional data synchronization between different clock frequencies is described wherein a state machine counter is provided a first clock signal having a first frequency. The state machine counter is then provided a second clock signal having a second frequency that is an integer multiple of the first clock frequency. The state machine counter has an integer number of states equivalent to the ratio of the second clock signal frequency to the first clock signal frequency. The first clock signal is applied to reset the state machine counter to an initial state. The state machine counter generates an intermediate clock signal whenever the state machine increments through all states to return to the initial state. The intermediate clock is then applied to synchronize data between the first clock frequency and the second clock frequency.
