ABSTRACT:
An output buffer for a semiconductor memory device and other semiconductor devices includes a feedback circuit to dynamically control the output impedance of the output buffer in response to a variety of load conditions, thus reducing output ringing. The output buffer may also include circuitry to support selectively converting the device for operation at a variety of supply voltage ranges without the need for additional mask or process steps.
