Abstract
A device includes a transistor switch coupled between a bit line voltage node and a ground node and a boost signal circuit coupled to a gate node of the transistor switch, where the boost signal circuit providing a boost signal responsive to a write enable signal. The device also includes a first delay element and a first capacitor in series with the first delay element. The first capacitor has a first end coupled to the bit line voltage node and a second end coupled to the gate node through the first delay element.
