Memory device with a sense amplifier detection circuit to control an output buffer amplifier

摘要

A memory device has an output buffer. The output buffer is electrically connected to a data output port of a sense amplifier of the memory device for amplifying an output signal from the data output port. The output buffer has a detector for producing a control signal according to the output signal from the data output port, and an amplifier for amplifying the output signal from the data output port. The amplifier has an input port electrically connected to the data output port for accepting the output signal from the data output port, and a control terminal electrically connected to the output terminal of the detector for accepting the control signal from the detector to control operations of the amplifier. When the detector produces the control signal and transmits the control signal to the control terminal of the amplifier, the amplifier begins amplifying the output signal transmitted from the data output port to the input port of the amplifier.
