Semiconductor systems and semiconductor devices

摘要

A semiconductor system includes a first semiconductor device and a second semiconductor device. The first semiconductor device outputs data, a data strobe signal, an external command, and a clock signal. The second semiconductor device aligns the data in synchronization with the data strobe signal to generate first and second alignment data and latches the first and second alignment data to generate first and second latch data in response to a latch signal which is generated by dividing the data strobe signal.

1. A semiconductor device comprising:
a latch signal generating circuit suitable for dividing a first internal strobe signal to generate a latch signal; and a data latch suitable for generating first and second latch data by latching first and second alignment data in response to the latch signal wherein the first and second alignment data is generated by aligning internal data in synchronization with the first internal strobe signal and a second internal strobe signal.
