Semiconductor devices including data aligner

摘要

The semiconductor device includes a first data aligner, an input strobe signal generator and a second data aligner. The first data aligner aligns input data in synchronization with an internal strobe signal to generate alignment data. The input strobe signal generator generates first and second delay signals from the internal strobe signal. The input strobe signal generator also latches an input clock signal generated from an external clock signal after a write latency period from a period when a write operation commences, in response to the first and second delay signals to generate an input strobe signal. The second data aligner re-aligns the alignment data in synchronization with the input strobe signal to generate internal data.

1. A semiconductor device comprising:
a first data aligner suitable for aligning input data in synchronization with an internal strobe signal to generate alignment data; an input strobe signal generator suitable for generating first and second delay signals from the internal strobe signal and latching an input clock signal generated from an external clock signal after a write latency period from a period when a write operation commences, in response to the first and second delay signals to generate an input strobe signal; and a second data aligner suitable for re-aligning the alignment data in synchronization with the input strobe signal to generate internal data, wherein the input strobe signal is enabled at a period when a pulse of the internal strobe signal is inputted to the input strobe signal generator after the input clock signal is generated.
