摘要： The layouts, device structures, and methods described above utilize dummy devices to extend the diffusion regions of edge structures and/or non-allowed structures to the dummy device. Such extension of diffusion regions resolves or reduces LOD and edge effect issues. In addition, treating the gate structure of a dummy device next to an edge device also allows only one dummy structure to be added next to the dummy device and saves the real estate on the semiconductor chip. The dummy devices are deactivated and their performance is not important. Therefore, utilizing dummy devices to extend the diffusion regions of edge structures and/or non-allowed structures according to design rules allows the resolution or reduction or LOD and edge effect issues without the penalty of yield reduction or increase in layout areas.

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.
