Abstract
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.
