Abstract
A circuit includes a first inverter, a second inverter, a first header circuit and a second header circuit. The first inverter is configured to convert a first global write signal into a first local write signal transmitted to a complement bit line. The second inverter is configured to convert a second global write signal into a second local write signal transmitted to a bit line. The first header circuit connects or disconnects a power terminal of the first inverter with a positive reference voltage supply in response to a write enable signal and the second global write signal. The second header circuit connects or disconnects a power terminal of the second inverter with the positive reference voltage supply in response to a write enable signal and the first global write signal.
