Abstract
A method and circuit are provided for maintaining an operating voltage on a selected column with a plurality of bitcells in a memory when writing to the selected column. The method includes during an active write operation to the selected column, implementing an NMOS transistor NC to allow a bitcell-supply self-discharge (BSSD) to occur on the selected column, wherein the BSSD occurs by connecting a first drain voltage to an operating voltage connection of the selected column via the NMOS transistor NC to allow discharge of the operating voltage connection while limiting over-discharge of the selected column. The method further includes a PMOS select transistor PS to connect a second drain voltage to the operating voltage connection of the unselected column.
