Abstract
A device is disclosed that includes a plurality of first memory cells, a plurality of second memory cells, a power circuit, and a header circuit. The power circuit is configured to provide a first power voltage via a conductive line for the plurality of first memory cells, and to provide a second power voltage, that is independent from the first power voltage, for the plurality of second memory cells. The header circuit is configured to provide, during the write operation, the first voltage smaller than the first power voltage, the second power voltage, or smaller than the first power voltage and the second power voltage, for corresponding memory cells of the plurality of first memory cells via the conductive line and for corresponding memory cells of the plurality of second memory cells. A circuit structure of the power circuit is different from a circuit structure of the header circuit.
