ABSTRACT:
A write driver system comprises first switching devices that generate gate drive signals. A write driver circuit includes second switching devices that are controlled by the gate drive signals. The second switching devices have higher voltage stress thresholds than the first switching devices and wherein the second switching devices have slower switching times than the first switching devices.
