In one embodiment, a memory includes a plurality of bit lines and a write driver for driving a driven bit line selected from the plurality of bit lines during a write operation. The write driver is coupled to an internal node. A first stage clamping circuit is operable to clamp the internal node to a clamping voltage if the write operation is not enabled and is further operable to unclamp the internal node during the write operation. The memory further includes a multiplexer for selectively coupling the driven bit line to the internal node. A second stage clamping circuit is operable to clamp the plurality of bit lines to a clamping voltage if the write operation is not enabled and is further operable to unclamp the driven bit line during the write operation.
