Abstract
A method for synchronizing signals includes the steps of receiving a preamble of a data strobe signal in response to a write preamble command, and synchronizing the data strobe signal with a clock signal through the preamble of the data strobe signal.
Claims5
A method of synchronizing signals, comprising the steps of:
- updating a synchronization operation between a clock signal and a data strobe signal when a write preamble command is inputted,
- wherein the updating the synchronization operation comprises;
- receiving a preamble of the data strobe signal in response to the write preamble command, and
- synchronizing the data strobe signal with the clock signal through the preamble of the data strobe signal;
- and
- wherein the updating the synchronization operation is not performed when a write command is inputted.

A method of processing data that is inputted in synchronization with a data strobe signal, comprising the steps of:
- performing a data processing operation after haying newly updated a synchronization operation between a clock signal and the data strobe signal when a write preamble command is inputted,
- wherein the performing the data processing operation comprises;
- receiving a preamble of the data strobe signal in response to the write preamble command;
- synchronizing timing of the data strobe signal with timing of the clock signal through the preamble of the data strobe signal;
- and
- processing data, which is input in synchronization with the data strobe signal, under a control of the data strobe signal and the clock signal,
- wherein the synchronization operation is not newly updated and the performing the data processing operation is only performed when a write command is inputted.

A method of processing data that is inputted in synchronization with a data strobe signal, comprising the steps of:
- receiving a preamble of the data strobe signal in response to a first write preamble command;
- synchronizing timing of the data strobe signal with timing of a clock signal through the preamble of the data strobe signal;
- processing first data, which is inputted in synchronization with the data strobe signal, under a control of the data strobe signal and the clock signal;
- processing second data, which is inputted in response to a first write command, under the control of the data strobe signal and the clock signal;
- receiving the preamble of the data strobe signal in response to a second write preamble command;
- resynchronizing the timing of the data strobe signal with the timing of the clock signal through the preamble of the data strobe signal;
- and
- processing third data, which is input in synchronization with the data strobe signal, under the control of the data strobe signal and the clock signal.
