ABSTRACT:
There is provided a dynamic output buffer useful for providing output data from a memory. The output buffer includes a cross coupled sense amplifier having inputs and outputs. The outputs of this sense amplifier are coupled by output transistors to the output of the dynamic output buffer. The outputs of the cross coupled sense amplifier are also coupled to dynamic load devices which are used to prevent the outputs from deteriorating when the inputs are shunted or clamped to ground. The inputs are clamped to ground by transistors which are controlled by timing signals and thereby insure that data stored by the cross coupled sense amplifier will not be lost.
