SEMICONDUCTOR DEVICES AND SEMICONDUCTOR SYSTEMS INCLUDING THE SAME

摘要

A semiconductor device may include a buffer control signal generation circuit, an input control signal generation circuit and an internal data generation circuit. The buffer control signal generation circuit may be configured to generate a buffer control signal. The buffer control signal may be enabled in synchronization with a point of time that a predetermined section elapses from a point of time that a write command signal is generated. The input control signal generation circuit may be configured to receive a data strobe signal to generate an input control signal, in response to the buffer control signal. The internal data generation circuit may be configured to receive a data signal to generate internal data.

1. The semiconductor system includes:
a data strobe signal buffer configured for buffering first and second data strobe signals to generate a first internal data strobe signal and a second internal data strobe signal, in response to buffer control signal; a first divider configured for generating third and fourth input control signals from first and second input control signals in synchronization with the first internal data strobe signal; and a second divider configured for generating the first and second input control signals from the third and fourth input control signals in synchronization with the second internal data strobe signal.
