Abstract
A data strobe signal generating circuit includes a pre-driver control unit for selectively transferring a ground voltage and a supply voltage, as a first control signal and a second control signal, in response to first and second clock pulse signals, wherein the second control signal is driven in response to a preamble signal, a pre-driver for generating a driving signal in response to the first and second control signals and the preamble signal, and an output buffer for driving an output pad in response to the driving signal.
Claims22
A data strobe signal generating circuit comprising:
- a pre-driver control unit for selectively transferring a ground voltage and a supply voltage, as a first control signal and a second control signal, in response to first and second clock pulse signals, wherein the second control signal is driven in response to a preamble signal;
- a pre-driver for generating a pull-up and pull-down driving signal in response to the first and second control signals and the preamble signal;
- and
- an output buffer for driving an output pad in response to the pull-up and pull-down driving signal.
